Documentation: minor grammatical fixes and rewording in git-bundle.txt
This commit also converts all reference specifications to a monospaced font,
as the embedded ~ character used in some of the references sometimes causes
the text up to the next ~ to be displayed incorrectly as a subscript when the
HTML pages are generated. This was tested with asciidoc 8.2.5.

diff --cached: do not borrow from a work tree when a path is marked as assume-unchanged
When the index says that the file in the work tree that corresponds to the
blob object that is used for comparison is known to be unchanged, "diff"
reads from the file and applies convert_to_git(), instead of inflating the
object, to feed the internal diff engine with, because an earlier
benchnark found that it tends to be faster to use this optimization.
However, the index can lie when the path is marked as assume-unchanged.
Disable the optimization for such paths.
Smudge the files fed to external diff and textconv
When preparing temporary files for an external diff or textconv, it is
easier on the external tools, especially when they are implemented using
platform tools, if they are fed the input after convert_to_working_tree().
This fixes msysGit issue 177.

When --pickaxe-regex is used, forward past the end of matches instead of
advancing to the byte after their start. This way matches count only
once, even if the regular expression matches their tail -- like in the
fixed-string fork of the code.
E.g.: /.*/ used to count the number of bytes instead of the number of
lines. /aa/ resulted in a count of two in "aaa" instead of one.
Also document the fact that regexec() needs a NUL-terminated string as
its second argument by adding an assert().

pack-objects: don't loosen objects available in alternate or kept packs
If pack-objects is called with the --unpack-unreachable option then it
will unpack (i.e. loosen) all unreferenced objects from local not-kept
packs, including those that also exist in packs residing in an alternate
object database or a locally kept pack. The only user of this option is
git-repack.
In this case, repack will follow the call to pack-objects with a call to
prune-packed, which will delete these newly loosened objects, making the
act of loosening a waste of time. The unnecessary loosening can be
avoided by checking whether an object exists in a non-local pack or a
locally kept pack before loosening it.
This fixes the 'local packed unreachable obs that exist in alternate ODB
are not loosened' test in t7700.

Propagate --exec-path setting to external commands via GIT_EXEC_PATH
Let PATH0=$PATH that was set before the invocation.
Let /foo be a build directory.
Let /pfx be the installation prefix.
Let pfxexecpath=/pfx/libexec/git-core.
The following is going on when 'git --exec-path=/foo gc' is invoked:
1. git sets PATH=/foo:$PATH0 using the path from --exec-path
2. gc execs 'git repack' (note: no dash).
3. Since there is a git in /foo (it's a build directory), /foo/git is
taken.
4. No explicit exec-path is set this time, hence, this secondary git sets
PATH=$pfxexecpath:/foo:$PATH
5. Since 'repack' is not a built-in, execv_dashed_external execs
'git-repack' (note: dash).
6. There is a $pfxexecpath/git-repack, and it is taken.
7. This git-repack runs 'git pack-objects' (note: no dash).
8. There is no git in $pfxexecpath, but there is one in /foo. Hence,
/foo/git is run.
9. pack-objects is a builtin, hence, in effect /foo/git-pack-objects
is run.
As you can see, the way in which we previously set the PATH allowed to
mix gits of different vintage. By setting GIT_EXEC_PATH when --exec-path
was given on the command line, we reduce the confusion.

t7700: demonstrate repack flaw which may loosen objects unnecessarily
If an unreferenced object exists in both a local pack and in either a pack

This option to pack-objects/rev-list was created to improve the -A and -a

found to be unnecessary since objects residing in local kept packs can be
filtered out by the --honor-pack-keep option.

pack-objects: only repack or loosen objects residing in "local" packs
These two features were invented for use by repack when repack will delete
the local packs that have been made redundant. The packs accessible
through alternates are not deleted by repack, so the objects contained in
them are still accessible after the local packs are deleted. They do not
need to be repacked into the new pack or loosened. For the case of
loosening they would immediately be deleted by the subsequent prune-packed
that is called by repack anyway.
This fixes the test
'packed unreachable obs in alternate ODB are not loosened' in t7700.

git-repack.sh: don't use --kept-pack-only option to pack-objects
The --kept-pack-only option to pack-objects treats all kept packs as equal.
This results in objects that reside in an alternate pack that has a .keep
file, not being packed into a newly created pack when the user specifies the
-a option to repack. Since the user may not have any control over the
alternate database, git should not refrain from repacking those objects
even though they are in a pack with a .keep file.
This fixes the 'packed obs in alternate ODB kept pack are repacked' test in
t7700.

t7700-repack: add two new tests demonstrating repacking flaws
1) The new --kept-pack-only mechansim of rev-list/pack-objects has
replaced --unpacked=. This new mechansim does not operate solely on
"local" packs now. The result is that objects residing in an alternate
pack which has a .keep file will not be repacked with repack -a.
This flaw is only apparent when a commit object is the one residing in
an alternate kept pack.
2) The 'repack unpacked objects' and 'loosen unpacked objects' mechanisms
of pack-objects, i.e. --keep-unreachable and --unpack-unreachable,
now do not operate solely on local packs. The --keep-unreachable
option no longer has any callers, but --unpack-unreachable is used when
repack is called with '-A -d' and the local repo has existing packs.
In this case, objects residing in alternate, not-kept packs will be
loosened, and then immediately deleted by repack's call to
prune-packed.
The test must manually call pack-objects to avoid the call to
prune-packed that is made by repack when -d is used.

Remove total confusion from git-fetch and git-push
The config file is not the only place remotes are defined, and without
consulting .git/remotes and .git/branches, you won't know if "origin" is
configured by the user. Don't give up too early and insult the user with
a wisecrack "Where do you want to fetch from today?"
The only thing the previous patch seems to want to prevent from happening
is a lazy "git fetch/push" that does not say where-from/to to produce an
error message 'origin not found', and we can do that by not letting
add_url_alias() to turn a nickname "origin" literally into a pathname
"origin" without changing the rest of the logic.

read-tree A B C: do not create a bogus index and do not segfault
"git read-tree A B C..." without the "-m" (merge) option is a way to read
these trees on top of each other to get an overlay of them.
An ancient commit ee6566e (Rewrite read-tree, 2005-09-05) passed the
ADD_CACHE_SKIP_DFCHECK flag when calling add_index_entry() to add the
paths obtained from these trees to the index, but it is an incorrect use
of the flag. The flag is meant to be used by callers who know the
addition of the entry does not introduce a D/F conflict to the index in
order to avoid the overhead of checking.
This bug resulted in a bogus index that records both "x" and "x/z" as a
blob after reading three trees that have paths ("x"), ("x", "y"), and
("x/z", "y") respectively. 34110cd (Make 'unpack_trees()' have a separate
source and destination index, 2008-03-06) refactored the callsites of
add_index_entry() incorrectly and added more codepaths that use this flag
when it shouldn't be used.
Also, 0190457 (Move 'unpack_trees()' over to 'traverse_trees()' interface,
2008-03-05) introduced a bug to call add_index_entry() for the tree that
does not have the path in it, passing NULL as a cache entry. This caused
reading multiple trees, one of which has path "x" but another doesn't, to
segfault.

Earlier, the rsync tests were disabled by default, as they needed a
running rsyncd daemon. This was only due to the limitation that our
rsync transport only allowed full URLs of the form
rsync://<host>/<path>
Relaxing the URLs to allow
rsync:<path>
permitted the change in the tests to run whenever rsync is available,
without requiring a fully configured and running rsyncd.

When there's no explicitly-named remote, we use the remote specified
for the current branch, which in turn defaults to "origin". But it
this case should require the remote to actually be configured, and not
fall back to the path "origin".
Possibly, the config file's "remote = something" should require the
something to be a configured remote instead of a bare repository URL,
but we actually test with a bare repository URL.
In fetch, we were giving the sensible error message when coming up
with a URL failed, but this wasn't actually reachable, so move that
error up and use it when appropriate.
In push, we need a new error message, because the old one (formerly
unreachable without a lot of help) used the repo name, which was NULL.

When memmem() was imported from glibc 2.2 into compat/, an optimization
was dropped in the process, in order to make the code smaller and simpler.
It was OK because memmem() wasn't used in performance-critical code. Now
the situation has changed and we can benefit from this optimization.
The trick is to avoid calling memcmp() if the first character of the needle
already doesn't match. Checking one character directly is much cheaper
than the function call overhead. We keep the first character of the needle
in the variable named point and the rest in the one named tail.

Use memmem() instead of open-coding it. The system libraries usually have a
much faster version than the memcmp()-loop here. Even our own fall-back in
compat/, which is used on Windows, is slightly faster.

Short story: There is a section in t3400 that tests fundamental rebase
properties. 3ec7371f (Add two extra tests for git rebase, 2009-02-09)
added a check that rebase works on a detached HEAD, but the test was put
near the end of the file. This moves it to a more suitable place.
Long story: The test that preceded the one in question tests that a
rebased commit degrades from a content change with mode change to a
mere mode change. But on Windows, where we have core.filemode=false,
the original commit did not record the mode change, and so the rebase
operation did not rebase anything. This caused the subsequent detached
HEAD test to fail.

There were actually two problems. This recipe created a situation where
git log would output a child commit after its parent. This meant that
we called fix_reversal which called splitvarc, which should call modify_arc
to note the fact that it has modified the arc that it has just split. It
wasn't, which meant that displayorder and other variables got into an
inconsistent state (a commit appearing twice in displayorder).
This then meant that the targetrow/targetid logic in drawvisible thought
it need to redraw each time. That, together with the fact that drawvisible
called drawcommits which called drawvisible if a redraw was needed, led
to the infinite loop.
In fact drawvisible is now the only caller of drawcommits. Thus, the
start and end row arguments to drawcommits always encompass the whole
visible area, so drawcommits doesn't need to call drawvisible to redraw;
it just needs to clear the screen and draw what it's been asked to.
This fixes these two problems by adding a call to modify_arc in
splitvarc and by taking out the call to drawvisible in drawcommits.
It also removes an unrelated left-over debugging puts in external_blame.
The parameters accepted by the --whitespace option of "git apply" have
changed over time, and the documentation for "git rebase" was out of
sync. Remove the specific parameter list from the "git rebase"
documentation and simply point to the "git apply" documentation for
details, as is already done in the "git am" documentation.

Now is_kept_pack() is just a member lookup into a structure, we can write
it as such.
Also rewrite the sole caller of has_sha1_kept_pack() to switch on the
criteria the callee uses (namely, revs->kept_pack_only) between calling
has_sha1_kept_pack() and has_sha1_pack(), so that these two callees do not
have to take a pointer to struct rev_info as an argument.
This removes the header file dependency issue temporarily introduced by
the earlier commit, so we revert changes associated to that as well.
This removes --unpacked=<packfile> parameter from the revision parser, and
rewrites its use in git-repack to pass a single --kept-pack-only option
instead.
The new --kept-pack-only option means just that. When this option is
given, is_kept_pack() that used to say "not on the --unpacked=<packfile>
list" now says "the packfile has corresponding .keep file".
