[PATCH 5/5] parse-options: use prefix_filename_except_for_dash() helper

[Jeff King <peff@peff.net>]

Since our fix_filename()'s only remaining special case is handling "-",
we can use the newly-minted helper function that handles this already.

If we do eventually find that "!file || !*file" is a sign of a bug, we
could perhaps just simplify this whole function away. :)
