[patch] switch to Emacs 23

[Boris Samorodov]

Hello All,

here is a patch to switch to Emacs 23 as a default. There are
50 affected ports. Tests were done at tinderbox. Please give
this patch a try. I'm going to fire up an exp run after some
testing. The patch is relative to PORTSDIR:

ftp://ftp.ipt.ru/pub/download/ports.diff.bz2

Changes to editors/emacs and Mk/bsd.emacs.mk were taken from
PR/137956 by Ashish SHUKLA (thanks!).

Those ports which define EMACS_PORT_NAME to be "emacs21" were
not touched (this time). They may be converted to the new
world order by removing the above mentioned assignment.

Four ports were marked as BROKEN with EMACS_PORT_NAME=emacs23
(they do not compile):
. lang/bigloo;
. mail/wanderlust;
. mail/wanderlust-devel;
. www/emacs-w3m.

Tree ports were marked as IGNORE with EMACS_PORT_NAME=emacs23:
. japanese/egg-canna (the port version is dated as of 2001,
  does not compile with Emacs 23 and seems it cannot be fixed);
. deskutils/remember.el (was incorporated into Emacs 23);
. editors/nxml (was incorporated into Emacs 23).

Enjoy.
