In a way, this is all a kludge anyway, because you do not see macro
invocations that are only visible through m4 expansion, from other
macro files, etc.  Only m4 can parse m4.  But we all knew that, and
still there is the bootstrapping issue ...

IMVHO you could just grep without word endings.  That's good enough
for this script.
