Yes, I agree with what you say.  I would actually rather see all of the
PLIST filtering done in an external script, since there isn't very much
reason to do it inline as we currently do in, and we may run
into variable length problems in make since the existing awk script is
machine-generated.  It's something that I may tackle after we branch.

Yes, we could encapsulate the awk callout in the external script, but
since the awk script is fixed, there isn't much benefit to having the
external script -- we can implement your idea without needing to add
anything extra to pkgsrc.

Yes, I handle this by capturing the output of the name expansion and
running it through "sort -u" to filter out duplicate names.

Yes, I think it'll be good to keep the PLIST as the master file list
instead of splitting off some bits into the package Makefile.
