[PATCH] _git: don't expand {alias} if _git-{alias} exists

["Benjamin R. Haskell" <zsh@benizi.com>]

From: "Benjamin R. Haskell" <zsh@benizi.com>

This allows easy creation of completion functions for aliases that are
shell wrappers around other git functions.

E.g. I have an alias for `git reset --hard` called `git hard`, which
checks that I'm not resetting staged changes:

$ git config alias.hard
! : reset hard unless staged ; if git diff --cached | grep -q . ; then echo You have staged changes ; return 1 ; fi ; git reset --hard

Adding the following function lets me use the same completion: _git-hard () { _git-reset "$@" }
