vcs-svn: suppress a signed/unsigned comparison warning
All callers pass a nonnegative delta_len, so the code is already safe.
Add an assertion to ensure that remains so and add a cast to keep
clang and gcc -Wsign-compare from worrying.

These are already safe because both sides of the comparison are
nonnegative.
This would normally not be important because Git is not -Wsign-compare
clean anyway, but we like to keep the vcs-svn/ lib to a higher
standard for convenience using it in other projects.

Avoiding it makes the code clearer and makes it easier for projects

Since the length of t is already known, we can simplify a little by
using memcmp() instead of strncmp() to carry out a prefix comparison.
All nearby code already does this.
Noticed in the standalone svn-dump-fast-export project which has not
needed to implement prefixcmp() yet.

vcs-svn: avoid self-assignment in dummy initialization of pre_off
Without this change, clang complains:
vcs-svn/svndiff.c:298:3: warning: Assigned value is garbage or undefined
off_t pre_off = pre_off; /* stupid GCC... */
^ ~~~~~~~
This code uses an old and common idiom for suppressing an
"uninitialized variable" warning, and clang is wrong to warn about it.
The idiom tells the compiler to leave the variable uninitialized,
which saves a few bytes of code size, and, more importantly, allows
valgrind to check at runtime that the variable is properly initialized
by the time it is used.
But MSVC and clang do not know that idiom, so let's avoid it in
vcs-svn/ code.
Initialize pre_off to -1, a recognizably meaningless value, to allow
future code changes that cause pre_off to be used before it is
initialized to be caught early.

push: don't guess at qualifying remote refs on deletion
When we try to push a ref and the right-hand side of the
refspec does not find a match, we try to create it. If it is
not fully qualified, we try to guess where it would go in
the refs hierarchy based on the left-hand source side. If
the source side is not a ref, then we give up and give a
long explanatory message.
For deletions, however, this doesn't make any sense. We
would never want to create on the remote side, and if an
unqualified ref can't be matched, it is simply an error. The
current code handles this already because the left-hand side
is empty, and therefore does not give us a hint as to where
the right-hand side should go, and we properly error out.
Unfortunately, the error message is the long "we tried to
qualify this, but the source side didn't let us guess"
message, which is quite confusing.
Instead, we can just be more succinct and say "we can't
delete this because we couldn't find it". So before:
$ git push origin :bogus
error: unable to push to unqualified destination: bogus
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to '$URL'
and now:
$ git push origin :bogus
error: unable to delete 'bogus': remote ref does not exist
error: failed to push some refs to '$URL'
It is tempting to also catch a fully-qualified ref like
"refs/heads/bogus" and generate the same error message.
However, that currently does not error out at all, and
instead gets sent to the remote side, which typically
generates a warning:
$ git push origin:refs/heads/bogus
remote: warning: Deleting a non-existent ref.
To $URL
- [deleted] bogus
While it would be nice to catch this error early, a
client-side error would mean aborting the push entirely and
changing push's exit code. For example, right now you can
do:
$ git push origin refs/heads/foo refs/heads/bar
and end up in a state where "foo" and "bar" are deleted,
whether both of them currently exist or not (and see an
error only if we actually failed to contact the server).
Generating an error would cause a regression for this use
case.

blame: compute abbreviation width that ensures uniqueness
Julia Lawall noticed that in linux-next repository the commit object 60d5c9f5 (shown with the default abbreviation width baked into "git
blame") in output from
diff-index.c: "git diff" has no need to read blob from the standard input
Only "diff --no-index -" does. Bolting the logic into the low-level
function diff_populate_filespec() was a layering violation from day
one. Move populate_from_stdin() function out of the generic diff.c
to its only user, diff-index.c.
Also make sure "-" from the command line stays a special token "read
from the standard input", even if we later decide to sanitize the
result from prefix_filename() function in a few obvious ways,
e.g. removing unnecessary "./" prefix, duplicated slashes "//" in
the middle, etc.
diff-index.c: unify handling of command line paths
Regardless of where in the directory hierarchy you are, "-" on the
command line means the standard input. The old code knew too much
about how the low level machinery uses paths to read from the
working tree and did not bother to have the same check for "-" when
the command is run from the top-level.
Unify the codepaths for subdirectory case and toplevel case into one
and make it clearer.
"git diff --no-index" takes exactly two paths, not pathspecs, and
has its own way queue_diff() to populate the diff_queue. Do not
call diff_tree_setup_paths(), pretending as it takes pathspecs.
Split a rather heavy-ish "git completion" script out to create a
separate "git prompting" script, to help lazy-autoloading of the
completion part while making prompting part always available.
Teach "git submodule" deal with nested submodule structure where a
module is contained within a module whose origin is specified as a
relative URL to its superproject's origin.
When "--simplify-merges/by-decoration" is given together with
"--first-parent" to "git log", the combination of these options
makes the simplification logic to use in-core commit objects that
haven't been examined for relevance, either producing incorrect
result or taking too long to produce any output. Teach the
simplification logic to ignore commits that the first-parent
traversal logic ignored when both are in effect to work around the
issue.
"git add" allows adding a regular file to the path where a submodule
used to exist, but "git update-index" does not allow an equivalent
operation to Porcelain writers.
Attempt to optimize matching with an exclude pattern with a deep
directory hierarchy by taking the part that specifies leading path
without wildcard literally.
Setting this to a URL prefix instead of a path to a local directory allows
git-help --web to work even when HTML docs aren't locally installed, by
pointing the browser at a copy accessible on the web. For example,
[help]

The original t9800 test code has a mix of assorted topics, some
of which are big enough to deserve their own homes.
Interdependencies between the topics make it confusing when
trying to study one in isolation. And it takes so long to run
that debugging an individual test is difficult.
Split out three big chunks of tests into their own files:
t9812-git-p4-wildcards.sh gets the 8 p4 wildcard tests
t9813-git-p4-preserve-users.sh gets the 4 --preserve-user tests
t9814-git-p4-rename.sh gets the 2 copy and rename tests
Test 9800 execution time drops from 29 sec to 9 sec. The

A path containing a space must be quoted when used as an
argument to either the copy or rename commands (because
unlike other commands, the path is not the final thing on
the line for those commands).
Commit 6280dfdc3b (fast-export: quote paths in output,
2011-08-05) previously attempted to fix fast-export's
quoting by passing all paths through quote_c_style().
However, that function does not consider the space to be a
character which requires quoting, so let's special-case the
space inside print_path(). This will cause space-containing
paths to also be quoted in other commands where such quoting
is not strictly necessary, but it does not hurt to do so.
The test from 6280dfdc3b did not detect this because, while
it does introduce renames in the export stream, it does not
actually turn on rename detection, so they were presented as
pairs of deletions/adds. Using "-M" reveals the bug.

rebases the current HEAD. This is because we try to match the number
of remainging arguments "$#", which fails to match "1" argument and

git credential fill: output the whole 'struct credential'
Instead of outputing only the username and password, print all the
attributes, even those that already appeared in the input.
This is closer to what the C API does, and allows one to take the exact

"git credential reject".
The credential API is in C, and not available to scripting languages.
Expose the functionalities of the API by wrapping them into a new
plumbing command "git credentials".
In other words, replace the internal "test-credential" by an official Git
command.

When running 'git diff --quiet <file1> <file2>', if file1 or file2
is outside the repository, it will exit(0) even if the files differ.
It should exit(1) when they differ.
This happens because 'diff_no_index' looks at the 'found_changes'
member from 'diff_options' to determine if changes were made. This
is the wrong thing to do, since it is only set if xdiff is actually
run and it finds a change (the diff machinery will optimize out the
xdiff call when it is not necessary) and in that case HAS_CHANGED
