indeed.  we'll also need to audit the current codebase for hard-coded regexes.

another instance that i happened upon tonight: the code for building
$buf-fname-expr in modes.c.  \\(, \\| and \\) are specified as
literals (see line l. 2453+)---they assume default metacharacter
settings.  a further grep of the tree suggests that the problem may be
quite widespread.
