Junio C Hamano 1e5f764c93 builtin-add.c: optimize -A option and "git add ." 
The earlier "git add -A" change was done in a quite inefficient
way (i.e. it is as unefficient as "git add -u && git add ." modulo
one fork/exec and read/write index).

When the user asks "git add .", we do not have to examine all paths
we encounter and perform the excluded() and dir_add_name()
processing, both of which are slower code and use slower data structure
by git standards, especially when the index is already populated.

Instead, we implement "git add $pathspec..." as:

 - read the index;

 - read_directory() to process untracked, unignored files the current
   way, that is, recursively doing readdir(), filtering them by pathspec
   and excluded(), queueing them via dir_add_name() and finally do
   add_files(); and

 - iterate over the index, filtering them by pathspec, and update only
   the modified/type changed paths but not deleted ones.

And "git add -A" becomes exactly the same as above, modulo:

 - missing $pathspec means "." instead of being an error; and

 - "iterate over the index" part handles deleted ones as well,
   i.e. exactly what the current update_callback() in builtin-add.c does.

In either case, because fill_directory() does not use read_directory() to
read everything in, we need to add an extra logic to iterate over the
index to catch mistyped pathspec.

////////////////////////////////////////////////////////////////

	GIT - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, depending on your mood.

 - random three-letter combination that is pronounceable, and not
   actually used by any common UNIX command.  The fact that it is a
   mispronunciation of "get" may or may not be relevant.
 - stupid. contemptible and despicable. simple. Take your pick from the
   dictionary of slang.
 - "global information tracker": you're in a good mood, and it actually
   works for you. Angels sing, and a light suddenly fills the room.
 - "goddamn idiotic truckload of sh*t": when it breaks

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.

Please read the file INSTALL for installation instructions.
See Documentation/tutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands,
and "man git-commandname" for documentation of each command.
CVS users may also want to read Documentation/cvs-migration.txt.

Many Git online resources are accessible from http://git.or.cz/
including full documentation and Git related tools.

The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org. To subscribe
to the list, send an email with just "subscribe git" in the body to
majordomo@vger.kernel.org. The mailing list archives are available at
http://marc.theaimsgroup.com/?l=git and other archival sites.

The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
