Hmmm, I see the following in referenced in various places in regex.c,
and it seems to be set by Emacs callers to the regex functions:
/* In Emacs, this is the string or buffer in which we
are matching. It is used for looking up syntax properties. */
Lisp_Object re_match_object;
search.c sets it to nil for the current buffer (and the string in the
case of a string); if word_boundary_p were just passed this object and
the position as extra arguments...?

Good question ... :-/
