qsort_safe already does this... I'll push a change to use that instead.

I think this change is misleading. user/group/mode/age can either be
NULL or "-" or should be set to a valid value. It should not be possible
to set them to an empty string. (Not that the change causes any problems,
just commenting on the fact that the patch description implies that it
changes stuff, but I don't see that.)
