I need to sit down and trace out the mechanics of the existing code to
understand the ways that invocation of a function can occur.  What I
wrote was:

----------------------------8< cut here >8------------------------------
The problem is how to decide if a function needs a new option; I haven't
looked too closely but I believe that functions are invoked from each
other directly via the Eprog code, rather than dispatch through the
shfunctab shfunc entries, so it's not viable to go via extending shfunc
(pity).
----------------------------8< cut here >8------------------------------

If I was wrong, and all function invocation goes via the shfunc entries,
then (a) that's much easier and (b) I'm very happy.
