And yet ... and yet ... if you adopt the position that what we're going
to print is "amproc item: referenced procedure", then it's not entirely
clear why the amproc item description shouldn't be complete. The
argument that it's redundant with the procedure description gets a lot
weaker as soon as you look at them as two separate items. Ditto amop.
And having to add a lot of otherwise-useless code to suppress the
redundancy surely isn't very attractive.
So I guess I'm coming around to the idea that we want something not too
much bigger than Andreas' original patch, but applying to both amop and
amproc, and putting the operator/function description at the end.
Comments?
