Junio C Hamano 6348624010 disallow branch names that start with a hyphen 
The current command line parser is overly lax in places and allows a
branch whose name begins with a hyphen e.g. "-foo" to be created, but the
parseopt infrastructure in general does not like to parse anything that
begins with a dash as a short-hand refname.  "git checkout -foo" won't
work, nor will "git branch -d -foo" (even though "git branch -d -- -foo"
works, it does so by mistake; we should not be taking anything but
pathspecs after double-dash).

All the codepaths that create a new branch ref, including the destination
of "branch -m src dst", use strbuf_check_branch_ref() to validate if the
given name is suitable as a branch name.  Tighten it to disallow a branch
that begins with a hyphen.

You can still get rid of historical mistakes with

  $ git update-ref -d refs/heads/-foo

and third-party Porcelains are free to keep using update-ref to create
refs with a path component that begins with "-".

Issue originally raised by Clemens Buchacher.

	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/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. 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.
