Hi Paul,
Was this patch ok?
Is submitting the patch by the mailing list appropriate, or
should I instead submit a bug (enhancement request) via savannah?
thanks,
Luke.

| Subject: [PATCH] doc: cross-reference m4 and gnulib regexp
|
| * doc/autoconf.texi: Add cross-references to the GNU M4 patsubst and
| regexp macros, and to the GNU Gnulib emacs regex section (since M4 is
| implemented using that, which is slightly different to the actual GNU
| Emacs regex syntax).
