[PATCH] git-quiltimport: fix security risk because of un-sanitized $level.

  I assume that nobody will have a series with -p1000 in it :)
  sorry for this gross mistake in the first place.

  [ for the inattentive readers $level was used without quoting, for
    good reasons as it's sometime empty and then we don't want to pass
    an empty argument to git-apply, though someone could use that to run
    arbitrary commands, not nice ]
