Cool.  You're already a step ahead of us.

Yes, wrapping fails for many cases.  It has advantages when we can
make it work though.

Wrapping probably isn't the right thing to do in general.  In fact
I suspect it's the wrong thing to do for the general fixincludes/fixinc
scripts since they are designed to work on many systems and those
systems are the ones most likely to need additional curses.h fixing.
