The sed provided by Solaris in /usr/xpg4/bin has a bug whereby an unanchored regex using * for zero or more repetitions sees two separate matches fed to the substitution engine in some cases. This is evidenced by: $ for sed in /usr/xpg4/bin/sed /usr/bin/sed /opt/csw/gnu/sed; do \ echo 'ab' | $sed -e 's|[a]*|X|g'; \ done XXbX XbX XbX This bug was triggered during a git submodule clone operation as exercised in the setup stage of t5526-fetch-submodules when using the default SANE_TOOL_PATH for Solaris. It led to paths such as ..../.. being used in the submodule .git gitdir reference. Using the expression 's|\([^/]*\(/*\)\)|..\2|g' provides the desired result with all three three tested sed implementations but is harder to read. As we do not need to handle fully qualified paths though, the expression could actually be [^/]+ which isn't properly handled either. Instead, use [^/][^/]*, as suggested by Andreas Schwab, which works on all three tested sed implementations. The new expression is semantically different than the original one. It will not place a leading '..' on a fully qualified path as the original expression did. All of the paths being passed through this regex are relative and did not rely on this behaviour so it's a safe change.

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 (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://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.
