What's in git.git

Executive Summary
=================

The 'maint' branch still has a handful more post v1.4.4.1
fixes.

Aside from the usual gitweb and git-svn updates, the 'master'
branch has one notable change that everybody should hopefully
welcome.  separate-remote layout is now the default for newly
cloned repositories.  We would be needing documentation updates
and probably some more minor fixes for fallout from this, but I
do not expect anything majorly broken.

Cooking in 'next' are handful topics:

 * "git shortlog bottom..top" can be used instead of a pipeline
   "git log bottom..top | git shortlog".

 * "git merge -m message <commit>" is another natural way to
   perform a local merge, in addition to the traditional
   "git pull . <localbranch>".  The former is more powerful in
   that it can take arbitrary <committish>, not just a ref.

 * The new "--depth $n" parameter to git clone/fetch tries to
   limit the commit ancestry depth to $n.  This still has known
   issues (for example, shallowly cloning the git.git repository
   and then deepening the result with large --depth parameter
   later does not seem to make the resulting repository fully
   connected, and fsck-objects reports corruption), so please
   handle it with care.

 * "git show-ref", especially the "-d" variant, is much more
   efficient when used in a repository with pack-pruned refs.

 * "git fetch" can fetch from a repository with pack-pruned refs
   over dumb protocol transports.

 * "git push $URL '':$ref" can be used to delete an existing ref
   from the remote side.

 * A glob pattern "Pull: refs/heads/*:refs/remotes/origin/*" is
   allowed in the remotes file.  The fetch can be forced by
   prefixing the specification with a '+'.

Currently 'pu' does not have much to speak of.

This update has rather large impact so the kernel list is CC'ed.
