rebase -i: correctly remember --root flag across --continue
d911d14 (rebase -i: learn to rebase root commit, 2009-01-02) tried to
remember the --root flag across a merge conflict in a broken way.
Introduce a flag file $DOTEST/rebase-root to fix and clarify.

This will be useful when somebody want to checkout something partially from
repository with some non-standart layout or exclude some files from it.
Example: repository has structure /module-{a,b,c}/{trunk,branches,tags}/...
Modules are interdependent, and you want it to be single repostory (to commit
to all modules simultaneously and view complete history), but do not want
branches and tags be checked out into working copy.
Other use case is excluding some large blobs.
The quirk for now is that user must specify this option every fetch/rebase;
in other case he may get extra files or "file not found" errors. It may be
will be resolved by adding regular expression to .git/config into

http-push: refactor lock-related headers creation for curl requests
DAV-related headers (more specifically, headers related to the lock token,
namely, If, Lock-Token, and Timeout) for curl requests are created and
allocated individually, eg a "if_header" variable for the "If: " header, a
"timeout_header" variable for the "Timeout: " header.
This patch provides a new function ("get_dav_token_headers") that creates
these header, saving methods from allocating memory, and from issuing a
"curl_slist_append()" call. The temporary string storage given to
curl_slist_append() is freed much earlier than the previous code with this
patch, but this change is safe, because curl_slist_append() keeps a copy
of the given string.
In part, this patch also addresses the fact that commit 753bc91 (Remove
the requirement opaquelocktoken uri scheme) did not update memory
allocations for DAV-related headers.

Rename detection: Avoid repeated filespec population
In diffcore_rename, we assume that the blob contents in the filespec
aren't required anymore after estimate_similarity has been called and thus
we free it. But estimate_similarity might return early when the file sizes
differ too much. In that case, cnt_data is never set and the next call to
estimate_similarity will populate the filespec again, eventually rereading
the same blob over and over again.
To fix that, we first get the blob sizes and only when the blob contents
are actually required, and when cnt_data will be set, the full filespec is
populated, once.

Makefile: use shell for-loop rather than Make's foreach loop during install
The install target uses a foreach loop to generate a single long shell
command line to handle installation of the built-in git commands. The
maximum length of the argument list varies by platform, and this use of
foreach quickly grows the length of the argument list. Current git can
exceed the default maximum argument list length on IRIX 6.5 of 20480
depending on the installation path.
Rather than using make's foreach loop to pre-generate the shell command
line, use a shell for-loop and allow the shell to iterate through each of
the built-in commands.

commit: more compact summary and without extra quotes
Update the report format again to save the screen real estates, while
avoiding from enclosing the one-line summary of the commit log inside
double quotes pair, which looks awkward when the message begins or ends
with a double quote. The old format looked like this:
Commit 5ef8d77a implemented color_parse_mem, a function for
parsing colors from a non-NUL-terminated string, by simply
allocating a new NUL-terminated string and calling
color_parse. This had a small but measurable speed impact on
a user format that used the advanced color parsing. E.g.,
# uses quick parsing
$ time ./git log --pretty=tformat:'%Credfoo%Creset' >/dev/null
real 0m0.673s
user 0m0.652s
sys 0m0.016s
# uses color_parse_mem
$ time ./git log --pretty=tformat:'%C(red)foo%C(reset)' >/dev/null
real 0m0.692s
user 0m0.660s
sys 0m0.032s
This patch implements color_parse_mem as the primary
function, with color_parse as a wrapper for strings. This
gives comparable timings to the first case above.

The $FIRSTLINE variable is from the user's commit and can contain
arbitrary backslash escapes that may be (mis)interpreted when given to
"echo", depending on the implementation. Use "printf" to work around the
issue.
Some SVN repositories contain git repositories within them
(hopefully accidentally checked in). Since git refuses to track
nested ".git" repositories, this can be a problem when fetching
updates from SVN.
Thanks to Morgan Christiansson for the report and testing.
The get_log() function in the Perl SVN API introduced the limit
parameter in 1.2.0. However, this got discarded in our SVN::Ra
compatibility layer when used with SVN 1.1.x. We now emulate
the limit functionality in older SVN versions by preventing the
original callback from being called if the given limit has been
reached. This emulation is less bandwidth efficient, but SVN
1.1.x is becoming rarer now.
Additionally, the --limit parameter in svn(1) uses the
aforementioned get_log() functionality change in SVN 1.2.x.
t9129 no longer depends on --limit to work and instead uses
Perl to parse out the commit message.
By default git-svn stores timestamps of fetched commits in
Subversion's UTC format. Passing --localtime to fetch will convert
them to the timezone of the server on which git-svn is run.
This makes the timestamps of a resulting "git log" agree with what
"svn log" shows for the same repository.

Since broken SVN clients can commit svn:special files without
the magic "link " prefix, this can affect delta application
when we update the broken svn:special file. So now we fall
back and retry the delta application on symlinks if having
a "link " prefix fails.
Our behavior differs from svn(1) (v1.5.1) slightly:
When a svn:special file is created w/o a "link " prefix, svn
will create a regular file (mode 100644 to git) with the
contents of the blob as-is.
Our behavior is to continue creating the symlink (mode 120000
to git) with the contents of the blob as-is. While this
differs from current svn(1) behavior, this is easier and more
efficient to implement (and the correctness of the svn(1) is
debatable, since it's a workaround for a bug in the first
place).
More information on this SVN bug is described here:
http://subversion.tigris.org/issues/show_bug.cgi?id=2692
git-svn: handle empty files marked as symlinks in SVN
Broken SVN clients generate empty files with the svn:special set
to '*'. This attempts to denote a symlink pointing to a file
with an empty path (""), which cannot be generated on a POSIX
system.
Thus, we mimic the behavior of svn(1) and create a zero-byte
file in our tree.
The "matching refs" semantics works only on matching branches these days.
Instead of using "heads" which traditionally has been used more or less
interchangeably with "refs", say "branch" explicitly here.

lstat_cache(): introduce invalidate_lstat_cache() function

lstat_cache(): introduce has_dirs_only_path() function
The create_directories() function in entry.c currently calls stat()
or lstat() for each path component of the pathname 'path' each and every
time. For the 'git checkout' command, this function is called on each
file for which we must do an update (ce->ce_flags & CE_UPDATE), so we get
lots and lots of calls.
To fix this, we make a new wrapper to the lstat_cache() function, and
call the wrapper function instead of the calls to the stat() or the
lstat() functions. Since the paths given to the create_directories()
function, is sorted alphabetically, the new wrapper would be very
cache effective in this situation.
To support it we must update the lstat_cache() function to be able to
say that "please test the complete length of 'name'", and also to give
it the length of a prefix, where the cache should use the stat()
function instead of the lstat() function to test each path component.

lstat_cache(): introduce has_symlink_or_noent_leading_path() function
In some cases, especially inside the unpack-trees.c file, and inside
the verify_absent() function, we can avoid some unnecessary calls to
lstat(), if the lstat_cache() function can also be told to keep track
of non-existing directories.
So we update the lstat_cache() function to handle this new fact,
introduce a new wrapper function, and the result is that we save lots
of lstat() calls for a removed directory which previously contained
lots of files, when we call this new wrapper of lstat_cache() instead
of the old one.
We do similar changes inside the unlink_entry() function, since if we
can already say that the leading directory component of a pathname
does not exist, it is not necessary to try to remove a pathname below
it!

lstat_cache(): more cache effective symlink/directory detection
Make the cache functionality more effective. Previously when A/B/C/D
was in the cache and A/B/C/E/file.c was called for, there was no match
at all from the cache. Now we use the fact that the paths "A", "A/B"
and "A/B/C" are already tested, and we only need to do an lstat() call
on "A/B/C/E".
We only cache/store the last path regardless of its type. Since the
cache functionality is always used with alphabetically sorted names
(at least it seems so for me), there is no need to store both the last
symlink-leading path and the last real-directory path. Note that if
the cache is not called with (mostly) alphabetically sorted names,
neither the old, nor this new one, would be very effective.
Previously, when symlink A/B/C/S was cached/stored in the symlink-
leading path, and A/B/C/file.c was called for, it was not easy to use
the fact that we already knew that the paths "A", "A/B" and "A/B/C"
are real directories.
Avoid copying the first path components of the name 2 zillion times
when we test new path components. Since we always cache/store the
last path, we can copy each component as we test those directly into
the cache. Previously we ended up doing a memcpy() for the full
path/name right before each lstat() call, and when updating the cache
for each time we have tested a new path component.
We also use less memory, that is, PATH_MAX bytes less memory on the
stack and PATH_MAX bytes less memory on the heap.

t7700: demonstrate misbehavior of 'repack -a' when local packs exist
The ability to "...fatten [the] local repository by packing everything that
is needed by the local ref into a single new pack, including things that are
borrowed from alternates"[1] is supposed to be provided by the '-a' or '-A'
options to repack when '-l' is not used, but there is a flaw. For each
pack in the local repository without a .keep file, repack supplies a
--unpacked=<pack> argument to pack-objects.
The --unpacked option to pack-objects, with or without an argument, causes
pack-objects to ignore any object which is packed in a pack not mentioned
in an argument to --unpacked=. So, if there are local packs, and
'repack -a' is called, then any objects which reside in packs accessible
through alternates will _not_ be packed. If there are no local packs, then
no --unpacked argument will be supplied, and repack will behave as expected.

There are three flags involved (-w -b and --ignore-space-at-eol) which
makes 8 combinations possible in total, but only 3 cases are tested (none,
