ctags fix for lisp (reposting)

[Ken Arnold%UCB]

Apparently my fix to my ctags program got truncataed at some sites.
I posted a version of ctags which recognized YACC and lex files, and
this is an update to it.  This is an editor script which will take
my posted ctags and (a) fix an introduced bug which prevented it
from recognizing lisp file, and (b) has ctags recognize the syntax
of "(defmethod", "(defwrapper" and "(defwhopper".  You MUST have
my posted ctags -- this will not work with the ctags source as
distributed by Berkeley (or anyone else).
