Variable: c-<>-notable-chars-re
c-<>-notable-chars-re is a buffer-local variable defined in
cc-engine.el.gz.
Documentation
A regexp matching any single character notable inside a <...> construct.
This must include "<" and ">", and should include ",", and
any character which cannot be valid inside such a construct.
This is used in c-forward-<>-arglist-recur to try to detect
sequences of tokens which cannot be a template/generic construct.
When "(" is present, that defun will attempt to parse a
parenthesized expression inside the template. When ")" is
present it will treat an unbalanced closing paren as a sign of
the invalidity of the putative template construct.
