Oh, now that I've had another look at portmaster's logic it
doesn't makes sense at all. What if distfiles of different
ports have similar %[-_]* names? What if different ports
require the same distfile of different versions? What if
distname changed radically? You can't make such broad
assumptions about distfile patterns. You should probably
do it the same way portsclean -D does - i.e. to check
"dist_subdir/distfile" against distinfo files of all installed
ports or all ports, whichever a user prefers.
