Those of us who prefer to avoid shell perlisms/bashisms (blessed by
POSIX' IBM/RH/Oracle-dominated board or not) appreciate your inclusion
of the equivalent sed regex.

`pkg rquery -a %n | grep -- '-[0-9]' | wc -l` shows only 40 ports (of
25096).  Doesn't seem like a whole lot or a difficult refactor but
perhaps we're missing the use case of this particular group.  Anyone
know why these 40 ports are so named?
