Severe egg on face

[John Mackin <john@syd.dit.csiro.au>]

_This_ time, I wrote:

    - 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!)

Heavy sighing is about all I can manage at this stage.  Of course,
this breaks in the simple degenerate case of a function named '.

I'm now pretty certain (although having been this stupid, I don't
feel too certain about anything :() that this can't be done with
grep-style regular expressions, and therefore can't be done with sed.
If anyone is interested in following that up, do let me know if
you succeed: the problem is that when you match a ', it's not a terminator
if it was preceded by [^']', but is one if it was preceded by ''
or [^'], and I don't think it's possible to express that in a grep RE.
I _believe_ it can be done with an egrep RE, and therefore the
task can be accomplished with awk -- but I am by no means
prepared to assert that definitely.  (Being wrong does terrible
things to my self-confidence.)

As a sop, I'm prepared to offer the thought that all this doesn't
matter that much, since the purpose of getting rid of functions
with -p is to prevent people `surprising' your script, and for
that purpose, functions with quoted names aren't going to matter
and could be ignored (and left in the environment).  This is
by no means _right_, though.  If it can't be done with awk,
the solution is to code it up in C...

OK,
John.
