When making a partial-commit, we need to prepare two index
files, one to be used to write out the tree to be committed
(temporary index) and the other to be used as the index file
after the commit is made.

The temporary index needs to be initialized to HEAD and then all
the named paths on the command line need to be staged on top of
the index.  For this, running add_files_to_cache() that compares
what is in the index and the paths given from the command line
is not enough -- the comparison will miss the paths that the
user previously ran "git add" to the index since the HEAD
because the index reset to the HEAD would not know about them.
The index file needs to get the same modification done when
preparing the temporary index as described above.

This implementation mimics the behaviour of the scripted
version of git-commit.  It first runs overlay_tree_on_cache(),
which was stolen from ls-files with the earlier change, to get
the list of paths that the user can potentially mean, and then
uses pathspec_match() to find which ones the user meant.  This
list of paths is used to update both the temporary and the real
index file.

Additional fixes are:

 - read the index file after pre-commit hook returns, as the
   hook can modify it to affect the contents of the commit.

 - remove the temporary index file .git/next-index-* after
   commit is done or aborted.

 - run post-commit hook with the real index file to be used
   after the commit (previously it gave the temporary commit if
   a partial commit was made).

 - resurrect the safety mechanism to refuse partial commits
   during a merge to match the scripted version.

This separates the logic to limit the extent of change to the
index by where you are (controlled by "prefix") and what you
specify from the command line (controlled by "pathspec").

This exports three helper functions from ls-files.

 * pathspec_match() checks if a given path matches a set of pathspecs
   and optionally records which pathspec was used.  This function used
   to be called "match()" but renamed to be a bit less vague.

 * report_path_error() takes a set of pathspecs and the record
   pathspec_match() above leaves, and gives error message.  This
   was split out of the main function of ls-files.

 * overlay_tree_on_cache() takes a tree-ish (typically "HEAD")
   and overlays it on the current in-core index.  By iterating
   over the resulting index, the caller can find out the paths
   in either the index or the HEAD.  This function used to be
   called "overlay_tree()" but renamed to be a bit more
   descriptive.

This function is used to see if a path given by the user does exist
on the filesystem.  A symbolic link that does not point anywhere does
exist but running stat() on it would yield an error, and it incorrectly
said it does not exist.

The rule is this: if the last line already contains the sign off by the

The Signed-off-by: line contained a spurious timestamp.  The reason was
a call to git_committer_info(1), which automatically added the
timestamp.

Instead, fmt_ident() was taught to interpret an empty string for the
date (as opposed to NULL, which still triggers the default behavior)
as "do not bother with the timestamp", and builtin-commit.c uses it.

When creating a bundle, symbolic refs used to be resolved to the
non-symbolic refs they point to before being written to the list
of contained refs.  I.e. "git bundle create a1.bundle HEAD master"
would show something like

388afe7881b33102fada216dd07806728773c011        refs/heads/master
388afe7881b33102fada216dd07806728773c011        refs/heads/master

instead of

388afe7881b33102fada216dd07806728773c011        HEAD
388afe7881b33102fada216dd07806728773c011        refs/heads/master

When using git-send-email with SMTP authentication sending a patch series
would redundantly authenticate multiple times, once for each patch. In
the worst case, this would actually prevent the series from being sent
because the server would reply with a "5.5.0 Already Authenticated"
status code which would derail the process.
