Indeed - once we realize that maint.mk implies the presence of perl (the 
implication is indirect: use of maint.mk rules implies that a maintainer is 
doing something, but being a maintainer implies the presence of autoconf which 
implies perl), it is much easier to ditch sed and grep altogether.

Is it worth trying to merge the sed and grep into a single process?

Fair enough.  So, do we apply your patch, or should I try testing/tweaking it 
further?
