[PATCH] Add git-branches-script

For people whose workflow involves switching back and forth between a
lot of branches, it can be really helpful to be able to quickly tell
which branch you are on and which ones are available.  This patch
introduces a small script that when invoked as `git branches' prints a
list of available branches with a star in front of the one you are on:

 $ cd linux-2.6/
 $ git checkout -b ppc64-cleanups
 $ git checkout -b ppc64-new-devel
 $ git checkout -b ppc64-all-merge
 $ git branches
   master
 * ppc64-all-merge
   ppc64-cleanups
   ppc64-new-devel
