Documentation: add missing quotes to "git grep" examples
Without an indication to the contrary, Asciidoc puts 'quoted
text' in italics, making the output look like this:
git grep time_t -- *.[ch]
Looks for time_t in all tracked .c and .h
files in the working directory and its subdirectories.
git grep -e '#define\' --and \( -e MAX_PATH -e PATH_MAX \)
Looks for a line that has #define and either MAX_PATH or
PATH_MAX.
In the first example, the *.[ch] argument needs to be protected from
the shell, or else it will only match files in the current directory.
The second example has a stray backslash.

Documentation: clarify quoting in "git add" example
The intended text looks like this:
· Adds content from all *.txt files under Documentation
directory and its subdirectories:
$ git add Documentation/\*.txt
Note that the asterisk * is quoted from the shell in this
example; this lets the command include the files from
subdirectories of Documentation/ directory.
The current asciidoc 8.5.2 output has a backslash before _every_
asterisk, which is more confusing than it needs to be.

I am not sure why, but the regular expression "(?:\^\{\})" gets
rendered by asciidoc as "(?:\{})". The intent seems to be a regex
matching the literal string "^{}", so this rewrites the markup to
produce "(?:\^{})" as output.

Documentation: quoting trouble in "git rm" discussion
The current output (with Asciidoc 8.5.2) seems a bit broken:
given two directories ‘d` and d2, there is a difference
between using git rm 'd*’ and ‘git rm 'd/\*\’`, as the
former will also remove all of directory d2.
In other words, the markup parses as
given two directories << d` and _d2_, there is a difference
between using _git rm 'd* >>_ and << git rm 'd/\*\ >> `.
I suspect there is an asciidoc bug involved (why is ' a candidate
closing-quote mark when it is preceded by a backslash?) but with
all the meanings of ` and ' involved I do not want to track it
down. Better to use unambiguous {asterisk} and {apostrophe}
entities.

When mergetool is run without path limiters it loops
over each entry in 'git ls-files -u'. This includes
autoresolved paths.
Teach mergetool to only merge files listed in 'rerere status'
when rerere is enabled.
There are some subtle but harmless changes in behavior.
We now call cd_to_toplevel when no paths are given.
We do this because 'rerere status' paths are always relative
to the root. This is beneficial for the non-rerere use as
well in that mergetool now runs against all unmerged files
regardless of the current directory.
This also slightly tweaks the output when run without paths
to be more readable.

Merging the files: foo

Currently git-svn assumes that two tags created from the same
revision will have the same repo url, so it uses a ref to the
tag without checking that its url matches the current url.
This causes issues when fetching an svn repo where a tag was
created, deleted, and then recreated under the following
circumstances:
- Both tags were copied from the same revision.
- Both tags had the same name.
- Both tags had different repository paths.
- [Optional] Both tags have a file with the same name but
different content.
When all four conditions are met, a checksum mismatch error
occurs because the content of two files with the same path
differs (see t/t9155--git-svn-fetch-deleted-tag.sh):
When only the first three conditions are met, no error occurs
but the tag in git matches the first (deleted) tag instead of
the last (most recent) tag (see
t/t9156-git-svn-fetch-deleted-tag-2.sh).
The fix is to verify that the repo url for the ref matches the
current url. If the urls do not match, then a "tail" is grown
on the tag name by appending a dash and rechecking the new ref's
repo url until either a matching repo url is found or a new tag
is created.

tags with names like "tags/mytag@5--@2" may be created.

diff --follow: do call diffcore_std() as necessary
Usually, diff frontends populate the output queue with filepairs without
any rename information and call diffcore_std() to sort the renames out.
When --follow is in effect, however, diff-tree family of frontend has a
hack that looks like this:
diff-tree frontend
-> diff_tree_sha1()
. populate diff_queued_diff
. if --follow is in effect and there is only one change that
creates the target path, then
-> try_to_follow_renames()
-> diff_tree_sha1() with no pathspec but with -C
-> diffcore_std() to find renames
. if rename is found, tweak diff_queued_diff and put a
single filepair that records the found rename there
-> diffcore_std()
. tweak elements on diff_queued_diff by
- rename detection
- path ordering
- pickaxe filtering
We need to skip parts of the second call to diffcore_std() that is related
to rename detection, and do so only when try_to_follow_renames() did find
a rename. Earlier 1da6175 (Make diffcore_std only can run once before a
diff_flush, 2010-05-06) tried to deal with this issue incorrectly; it
unconditionally disabled any second call to diffcore_std().
diff --follow: do not waste cycles while recursing
The "--follow" logic is called from diff_tree_sha1() function, but the
input trees to diff_tree_sha1() are not necessarily the top-level trees
(compare_tree_entry() calls it while it recursively descends into
subtrees). When a newly created path lives in somewhere deep in the
source hierarchy, e.g. "platform/", but the rename source is in a totally
different place in the destination hierarchy, e.g. "lang-api/src/com/...",
running "try_to_find_renames()" while base is set to "platform/" is a
wasted call.
We only need to run the rename following at the very top level.

There are two ways a user might want to use "diff --relative":
1. For a file in a directory, like "subdir/file", the user
can use "--relative=subdir/" to strip the directory.
2. To strip part of a filename, like "foo-10", they can
use "--relative=foo-".
We currently handle both of those situations. However, if the user passes
"--relative=subdir" (without the trailing slash), we produce inconsistent
results. For the unified diff format, we collapse the double-slash of
"a//file" correctly into "a/file". But for other formats (raw, stat,
name-status), we end up with "/file".
We can do what the user means here and strip the extra "/" (and only a
slash). We are not hurting any existing users of (2) above with this
behavior change because the existing output for this case was nonsensical.

When you have a lot of submodules checked out, the time penalty to check
for dirty submodules can easily imply a multiplication of the total time
by the factor 20. This makes the difference between almost instantaneous
(< 2 seconds) and unbearably slow (> 50 seconds) here, since the disk
caches are constantly overloaded.
To this end, the submodule.*.ignore config option was introduced, but it
is per-submodule.
This commit introduces a global config setting to set a default
(porcelain) value for the --ignore-submodules option, keeping the
default at 'none'. It can be overridden by the submodule.*.ignore
setting and by the --ignore-submodules option.
Incidentally, this commit fixes an issue with the overriding logic:
multiple --ignore-submodules options would not clear the previously
set flags.

Submodules: Add the new "ignore" config option for diff and status
The new "ignore" config option controls the default behavior for "git
status" and the diff family. It specifies under what circumstances they
consider submodules as modified and can be set separately for each
submodule.
The command line option "--ignore-submodules=" has been extended to accept
the new parameter "none" for both status and diff.
Users that chose submodules to get rid of long work tree scanning times
might want to set the "dirty" option for those submodules. This brings
back the pre 1.7.0 behavior, where submodule work trees were never
scanned for modifications. By using "--ignore-submodules=none" on the
command line the status and diff commands can be told to do a full scan.
This option can be set to the following values (which have the same name
and meaning as for the "--ignore-submodules" option of status and diff):
"all": All changes to the submodule will be ignored.
"dirty": Only differences of the commit recorded in the superproject and
the submodules HEAD will be considered modifications, all changes
to the work tree of the submodule will be ignored. When using this
value, the submodule will not be scanned for work tree changes at
all, leading to a performance benefit on large submodules.
"untracked": Only untracked files in the submodules work tree are ignored,
a changed HEAD and/or modified files in the submodule will mark it
as modified.
"none" (which is the default): Either untracked or modified files in a
submodules work tree or a difference between the subdmodules HEAD
and the commit recorded in the superproject will make it show up
as changed. This value is added as a new parameter for the
"--ignore-submodules" option of the diff family and "git status"
so the user can override the settings in the configuration.

Since there are WEBrick configuration settings (including the
upcoming AccessLog support) that cannot be represented in YAML
and require Ruby anyways, the YAML config file is an unnecessary
layer of complexity.
Additionally, the shell script wrapper to start WEBrick is
unecessary since our generated Ruby script can be made
executable in the same manner with /usr/bin/env.
This has been broken since commit be5347b ("httpd logs in a
"$httpd_only" subdirectory").
Since WEBrick has no other way of preserving environment
variables needed for gitweb, we create a shell script wrapper
that sets the environment variables as our CGI interpreter
to run gitweb.cgi.
