bug#9784: 24.0.50; vc-git-stash-show not escaping name

From: João Távora
Subject: bug#9784: 24.0.50; vc-git-stash-show not escaping name
Date: Tue, 18 Oct 2011 15:48:21 +0100
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.0.50 (windows-nt)

1. Start emacs -Q
2. Find a file in a git repository with a stash named address@hidden
3. Try to show a stash
4. Be presented with an error message like

    fatal: ambiguous argument 'address@hidden': unknown revision or path not in 
the working tree.
    Use '--' to separate paths from revisions

The problem seems to happen because the curly braces in the stash name
aren't shell-quoted. Using `shell-quote-argument' in `vc-git-command'

(defun vc-git-command (buffer okstatus file-or-list &rest flags)
  "A wrapper around `vc-do-command' for use in vc-git.el.
The difference to vc-do-command is that this function always invokes
  (apply 'vc-do-command (or buffer "*vc*") okstatus vc-git-program
         file-or-list (mapcar #'shell-quote-argument flags)))
