Since Git 2.0, "add -u" and "add -A" run from a subdirectory without any pathspec mean "everything in the working tree" (before 2.0, they were limited to the current directory). The limiting to the current directory was implemented by inserting "." to the command line when the end user did not give us any pathspec. At 2.0, we updated the code to insert ":/" (instead of '.') to consider everything from the top-level, by using a pathspec magic "top". The call to parse_pathspec() using the command line arguments is, however, made with PATHSPEC_PREFER_FULL option since 5a76aff1 (add: convert to use parse_pathspec, 2013-07-14), which predates Git 2.0. In retrospect, there was no need to turn "adding . to limit to the directory" into "adding :/ to unlimit to everywhere" in Git 2.0; instead we could just have done "if there is no pathspec on the command line, just let it be". The parse_pathspec() then would give us a pathspec that matches everything and all is well. Incidentally such a simplification also fixes a corner case bug that stems from the fact that ":/" does not necessarily mean any magic. A user would say "git --literal-pathspecs add -u :/" from the command line when she has a directory ':' and wants to add everything in it (and she knows that her :/ will be taken as 'everything under the sun' magic pathspec unless she disables the magic with --literal-pathspecs). The internal use of ':/' would behave the same way as such an explicitly given ":/" when run with "--literal-pathspecs", and will not add everything under the sun as the code originally intended.

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 version 2 (some parts of it are under different licenses,
compatible with the GPLv2). It was originally written by Linus
Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".
CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).
Many Git online resources are accessible from http://git-scm.com/
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 (read
Documentation/SubmittingPatches for instructions on patch submission).
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://news.gmane.org/gmane.comp.version-control.git/,
http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the "What's cooking" reports that
list the current status of various development topics to the mailing
list. The discussion following them give a good reference for
project status, development direction and remaining tasks.
