Adding email address support to thingatpt.el. |

I was surprised to find that thingatpt.el doesn't support email
addresses, so made the patch below. I'd like comments before
committing, though, as I've never modified thingatpt.el before.
If we're in a freeze, this can wait. (I can't tell if we're in a
freeze or not, from looking at the Savannah pages for Emacs.)

* thingatpt.el: Add support for email addresses (`email').
(thing-at-point, bounds-of-thing-at-point): Document `email' support.
(thing-at-point-email-regexp): New variable.
(`email'): Put `bounds-of-thing-at-point' and `thing-at-point'
properties on this symbol, with lambda forms for values.
