Attached to this message you can find a series of patches to the
git completion file (installed as
/usr/share/zsh/4.3.2/functions/Completion/Unix/_git, no idea where
it lives in the source tree).  The five patches are base upon each
other and need to be applied in order.  I've split them up for
better readability.

0001*

  Removes trailing whitespace from the file.

0002*

  Fixes a syntax error in the completion code for git-clone.  Also
  replaces $* with $@ in some places and fixes a TODO in
  _git-rev-list.

0003*

  Adds completion of generic git options like "git --git-dir"

0004*

  Ports bash's completion code for heads, tags, branches etc. to
  zsh.  This code is *much* faster because is does not depend on
  the git-ls-remote command, does not require a network connection
  (for the same reason) and also properly handles the --git-dir
  argument as well as the GIT_DIR environment variable (for all
  git commands).

  Finally it rewrites the completion code of git-branch completely
  so that it works in all modes (list/create/delete/move
  branches).
