    You can't really do without the two rev's, [...]

Apologies to all on the list, I must've been drunk :).  Sheesh, do I
feel like a silly person; the above, of course, _still_ doesn't work
in the presence of function names containing {.  Anyway it can be done,
but I don't have time now to fully test an implementation, and rather
than mail another implementation that isn't fully tested, I'll just
describe how to write the sed:

- any line beginning with "fn " either does or doesn't begin with "fn '"
- if it doesn't, then the function name terminates at the second
  space character on the line
- if it does, then the function name terminates at the first "'" character
  following the "'" character in "fn '" which is not preceded by a "'"
  (wow, thank Duff for rc's simple, consistent quoting rules!)

And you don't need any rev's, just the sed.

Hangs head in shame....

OK,
John.
