[PATCH] vcs_info: examples: use sed's q1 with +vi-git-untracked

[Daniel Hahler <genml+zsh-workers@xxxxxxxxxx>]

From: Daniel Hahler <git@xxxxxxxxxx>

This short-circuits the git command if there is any match.

Especially with `git ls-files` this is faster, although the additional
`--directory` (to only display directories, if they are untracked
completely, instead of all files in there) might make up for most of it.
