How about this: simply check for files with a `.' in, and only do more
powerful processing when stripping suffixes.  The processing is: attempt to
strip a known compression suffix (this is the only place where these need
to go now), then attempt to strip the _minimum_ suffix beginning with a dot
and a number (separating these into separate expansions means they always
both get tried --- btw extendedglob didn't seem to get set for that `##' in
the old version).  This handles cases like Solaris's POSIX.1.5 (i.e. the
manual entry for POSIX.1 in man5).  If Andrej has entries with similar
names like POSIX.1.Z, then we're out of luck and will have to resort to
some extra processing to decide the current system's format.
