Messages crossed ...

If it were me, I would combine that DETAIL and HINT as one larger HINT,
and use DETAIL for specific details about what actually happened (such
as the exact filename sought and the %m).

The need for those details doesn't go away; they're still what you need
when what went wrong is some other freak occurrence the hint doesn't
explain.
