Using "grep -q" would probably solve it already for the "git status"
case (which uses grep already), and "| grep -q ." could be used for
"git ls-files".

I've also found that "git status" can be noticably slower than "ls-files",
so I'd suggest to use this instead.

Additionally, the hook appears to be only called if there's a gitdir anyway,
so the check ("git rev-parse --is-inside-work-tree") could be removed.

I am using this currently:

  # vcs_info: git: Show marker (✗) if there are untracked files in repository.
  # (via %c).
  function +vi-git-untracked() {
      [[ $1 == 0 ]] || return  # do this only once for vcs_info_msg_0_.

      local gitdir=${vcs_comm[gitdir]}

      if command git --git-dir $gitdir ls-files --other --directory --exclude-standard | command grep -q .; then
          hook_com[staged]+='✗ '
      fi
  }


What do you think?
Should I update the patch?

Daniel.
