In the !delta_data error path of unpack_entry(), we run free(base).
This became a window for use-after-free() in abe601b (sha1_file:
remove recursion in unpack_entry, 2013-03-27), as follows:
Before abe601b, we got the 'base' from cache_or_unpack_entry(..., 0);
keep_cache=0 tells it to also remove that entry. So the 'base' is at
this point not cached, and freeing it in the error path is the right
thing.
After abe601b, the structure changed: we use a three-phase approach
where phase 1 finds the innermost base or a base that is already in
the cache. In phase 3 we therefore know that all bases we unpack are
not part of the delta cache yet. (Observe that we pop from the cache
in phase 1, so this is also true for the very first base.) So we make
no further attempts to look up the bases in the cache, and just call
add_delta_base_cache() on every base object we have assembled.
But the !delta_data error path remained unchanged, and now calls
free() on a base that has already been entered in the cache. This
means that there is a use-after-free if we later use the same base
again.
So remove that free(); we are still going to use that data.

The only reason I wrapped this code around a sub-function is because zsh
did the same in it's bashcompinit script in order to declare the special

There's no need for that any more since we access __git_main directly,

removed the smoke test support from the test suite but it was
re-added by commit 342e9ef (Introduce a performance testing

pretty: Fix bug in truncation support for %>, %< and %><
Some systems experience failures in t4205-*.sh (tests 18-20, 27)
which all relate to the use of truncation with the %< padding
placeholder. This capability was added in the commit a7f01c6b
("pretty: support truncating in %>, %< and %><", 19-04-2013).
The truncation support was implemented with the assistance of a
new strbuf function (strbuf_utf8_replace). This function contains
the following code:
Unfortunately, this code is subject to unspecified behaviour. In
particular, the order of evaluation of the argument expressions
(along with the associated side effects) is not specified by the
C standard. Note that the second argument expression is a call to
strbuf_detach() which, as a side effect, sets the 'len' and 'alloc'
fields of the sb_dst argument to zero. Depending on the order of
evaluation of the argument expressions to the strbuf_attach call,
this can lead to assigning an empty string to 'sb_src'.
In order to remove the undesired behaviour, we replace the above
line of code with:
Sparse issues an "'junk_mode' not declared. Should it be static?"
warning. In order to suppress the warning, since this symbol does
not need more than file visibility, we simply add the static
modifier to its declaration.

git add: avoid "-u/-A without pathspec" warning on stat-dirty paths
In preparation for Git 2.0, "git add -u/-A" without pathspec checks
all the working tree (not limited to the current directory) and
issues a warning when it finds any path that we might add in Git
2.0, because that would mean the users' fingers need to be trained
to explicitly say "." if they want to keep the current behaviour.
However, the check was incomplete, because "git add" usually does
not refresh the index, considers a path that is stat-dirty but has
contents that is otherwise up-to-date in the index as "we might
add", and relies on that it is a no-op to add the same thing again
via the add_file_to_index() API (which also knows not to say "added"
in verbose mode when this happens). We do not want to trigger the
warning for a path that is outside the current directory is merely
stat-dirty, as it won't be added in Git 2.0, either.

bash-prompt.sh: show where rebase is at when stopped
When a rebase stops (e.g. interrupted by a merge conflict), it could
be useful to know how far a rebase has progressed and how many
commits in total this rebase will apply. Teach the __git_ps1()
command to display the number of commits so far applied and the
total number of commits to be applied, like this:
In the example above the rebase has stopped at the second commit due to
a merge conflict and there are a total number of five commits to be
applied by this rebase.
This information can be already obtained from the following files which are
being generated during the rebase:
"git merge $(git rev-parse v1.8.2)" behaved quite differently from
"git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
not pay much attention to the annotated tag payload. Make the code
notice the type of the tag object, in addition to the dwim_ref()
based classification the current code uses (i.e. the name appears in
refs/tags/) to decide when to special case merging of tags.

according to its current documentation. All but 'set-branches' and
'update' are listed as taking only a fixed number of arguments; for
those we can write a test with one more (bogus) argument, and see if
the command notices that.
They fail on several counts: 'add' does not check for extra arguments,
and 'show' and 'prune' actually iterate over remotes (i.e., take any
number of args). We'll fix them in the next two patches.

When we 'git rebase $upstream', git uses 'rev-parse --verify
$current_branch' to find ORIG_HEAD. But if $current_branch
is ambiguous, 'rev-parse --verify' emits a warning and returns
a SHA1 anyway. When the wrong ambiguous choice is used,
git-rebase fails non-gracefully: it emits a warning about
failing to lock $current_branch, an error about being unable to
checkout $current_branch again, and it might even decide the
rebase is a fast-forward when it is not.
In the 'rebase $upstream' case, we already know the unambiguous
spelling of $current_branch is "HEAD". Fix git-rebase to find
$orig_head unambiguously.

name and rebases it implicitly with 'git rebase $other'.
