What's in git.git (stable)

[Junio C Hamano <junkio@cox.net>]

We have a handful fixes on 'maint'; I will be cutting v1.4.4.3 by
the end of the week.

On the 'master' front, this round has many topics (most of which
have been cooking in the 'next' branch) merged since the last
announcement.

 - Johannes Schindelin's built-in shortlog is in.

 - Johannes Schindelin's built-in 'RCS merge replacement' is
   in.  Hopefully this would make merge-recursive more portable
   and faster.

 - Shawn Pearce and Johannes Schindelin spotted and fixed a few
   corner cases in merge-recursive.

 - Updates to gitk from Paul Mackerras to fix longstanding menu
   issues on Mac OS X.

 - Eric Wong fixed use of rerere in many places.

 - Eric also has quite a few fixes to git-svn.

 - Nico updated 'git-add' to really mean 'add contents', not
   'add to the set of tracked paths'.  Also updated was the
   documentation for 'git commit' to make it easier to teach new
   people after a long discussion.

 - Lars Hjemli taught 'git-branch' to rename branches.

 - Andy Parkins taught 'git-branch' to be colorful.

 - Robin Rosenberg improved cvsexportcommit for unusual
   pathnames.

 - 'git push $URL :refs/tags/that' (notice the colon) can be
   used to delete 'that' tag from the remote repository; this
   needs the latest git on both ends.

 - branch."master".{remote,merge} configuration items are set up
   by 'git-clone', thanks to Andy Parkins.

 - 'git-commit' gives 'diff --summary' output to remind mode
   changes and added/deleted files.

 - 'git-diff --numstat' matches 'git-apply --numstat' when
   talking about binary changes.

 - 'git-merge' is now a first class UI, not just a mere driver
   for strategies.

I am hoping that we can start a stabilization cycle for v1.5.0
based on what we have in 'master'.  The theme is "usability and
teachability".

Things that need to be done to complete what have been merged to
'master' are:

 - 'git-rm' needs to be fixed up as Linus outlined; remove
   working tree file and index entry but have a sanity check to
   make sure the working tree file match the index and HEAD.

 - 'git-branch' may need to be taught about renaming the
   matching per-branch configuration at the same time.

 - 'git-merge-file' needs to be documented and linked from
   git.txt.

 - 'git-clone' probably should be updated to use wild-card in
   remote.origin.fetch, instead of listing all the branches it
   found when the clone was made.

 - tutorials and other Porcelain documentation pages need to be
   updated to match the updated 'git-add' and 'git-rm' (to be
   updated), and their description should be made much less
   about implementation; they should talk in terms of end-user
   workflows.  I will send a draft for 'git diff' out later, but
   somebody needs a full sweep on Porcelain-ish documentation.

 - 'git diff --index' patch should be reverted (already done in
   'next'), although we may have to come up with a better
   wording for --cached.
