Insofar as this is an extremely well-documented limitation of MS-DOS, the
problem IS lharc's.  A multi-platform file utility should detect this and
take appropriate action.

On the contrary, Kai Uwe Rommel's extended version of lharc handles this
with reasonable facility.  All dots but the last get mapped to underscores,
and either DOS or lharc truncates any "overhang."  Unfortunately, there are
one or two other bugs which don't appear in the just-DOS version...
