git-completion.bash: add support for path completion
The git-completion.bash script did not implemented full, git aware,
support to complete paths, for git commands that operate on files within
the current working directory or the index.
As an example:
git add <TAB>
will suggest all files in the current working directory, including
ignored files and files that have not been modified.
Support path completion, for git commands where the non-option arguments
always refer to paths within the current working directory or the index,
as follows:
* the path completion for the "git rm" and "git ls-files"
commands will suggest all cached files.
* the path completion for the "git add" command will suggest all
untracked and modified files. Ignored files are excluded.
* the path completion for the "git clean" command will suggest all
untracked files. Ignored files are excluded.
* the path completion for the "git mv" command will suggest all cached
files when expanding the first argument, and all untracked and cached
files for subsequent arguments. In the latter case, empty directories
are included and ignored files are excluded.
* the path completion for the "git commit" command will suggest all
files that have been modified from the HEAD, if HEAD exists, otherwise
it will suggest all cached files.
For all affected commands, completion will always stop at directory
boundary. Only standard ignored files are excluded, using the
--exclude-standard option of the ls-files command.
When using a recent Bash version, Git path completion will be the same
as builtin file completion, e.g.
git add contrib/
will suggest relative file names.

fetch: add --unshallow for turning shallow repo into complete one
The user can do --depth=2147483647 (*) for restoring complete repo
now. But it's hard to remember. Any other numbers larger than the
longest commit chain in the repository would also do, but some
guessing may be involved. Make easy-to-remember --unshallow an alias
for --depth=2147483647.
Make upload-pack recognize this special number as infinite depth. The
effect is essentially the same as before, except that upload-pack is
more efficient because it does not have to traverse to the bottom
anymore.
The chance of a user actually wanting exactly 2147483647 commits
depth, not infinite, on a repository with a history that long, is
probably too small to consider. The client can learn to add or
subtract one commit to avoid the special treatment when that actually
happens.

log --use-mailmap: optimize for cases without --author/--committer search
When we taught the commit_match() mechanism to pay attention to the
new --use-mailmap option, we started to unconditionally copy the
commit object to a temporary buffer, just in case we need the author
and committer lines updated via the mailmap mechanism, and rewrite
author and committer using the mailmap.
It turns out that this has a rather unpleasant performance
implications. In the linux kernel repository, running
$ git log --author='Junio C Hamano' --pretty=short >/dev/null
under /usr/bin/time, with and without --use-mailmap (the .mailmap
file is 118 entries long, the particular author does not appear in
it), cost (with warm cache):
The latter case is an unnecessary performance regression. We may
want to _show_ the result with mailmap applied, but we do not have
to copy and rewrite the author/committer of all commits we try to
match if we do not query for these fields.
Trivially optimize this performace regression by limiting the
rewrites for only when we are matching with author/committer fields.

mailmap: remove email copy and length limitation
In map_user(), we have email pointer that points at the beginning of
an e-mail address, but the buffer is not terminated with a NUL after
the e-mail address. It typically has ">" after the address, and it
could have even more if it comes from author/committer line in a
commit object. Or it may not have ">" after it.
We used to copy the e-mail address proper into a temporary buffer
before asking the string-list API to find the e-mail address in the
mailmap, because string_list_lookup() function only takes a NUL
terminated full string.
Introduce a helper function lookup_prefix that takes the email
pointer and the length, and finds a matching entry in the string
list used for the mailmap, by doing the following:
- First ask string_list_find_insert_index() where in its sorted
list the e-mail address we have (including the possible trailing
junk ">...") would be inserted.
- It could find an exact match (e.g. we had a clean e-mail address
without any trailing junk). We can return the item in that case.
- Or it could return the index of an item that sorts after the
e-mail address we have.
- If we did not find an exact match against a clean e-mail address,
then the record we are looking for in the mailmap has to exist
before the index returned by the function (i.e. "email>junk"
always sorts later than "email"). Iterate, starting from that
index, down the map->items[] array until we find the exact record
we are looking for, or we see a record with a key that definitely
sorts earlier than the e-mail we are looking for (i.e. when we
are looking for "email" in "email>junk", a record in the mailmap
that begins with "emaik" strictly sorts before "email", if such a
key existed in the mailmap).
This, together with the earlier enhancement to support
case-insensitive sorting, allow us to remove an extra copy of email
buffer to downcase it.
A part of this is based on Antoine Pelisse's previous work.

When enumerating paths that are ignored, paths the index knows

name hash, and ignored ones are shown as ignored (directories
can never be tracked anyway).
- When core.ignorecase is true, however, the name hash keeps
track of the names of directories, in order to detect
additions of the paths under different cases. This causes
ignored directories to be mistakenly excluded when
enumerating ignored paths.
Stop excluding directories that are in the name hash when
looking for ignored files in dir_add_name(); the names that are
