Indeed, and the comment in `dired-between-files' suggests using
(save-excursion (not (dired-move-to-filename))) which basically just
ends up using dired-permission-flags-regexp as you suggest (that regexp
can't be used directly with looking-at, because it doesn't match from
the beginning of a line).

The following patch seems to do the right thing in a non-english locale,
without any message dependencies; despite the comment it's not
perceptibly slow for me:
