Subject: 23.1.90; Get rid of Rmail's constant swapping of text between rmail-buffer and rmail-view-buffer
Date: Fri, 11 Dec 2009 14:09:22 +0200

Rmail calls buffer-swap-text too much.  Related discussions concluded
that this is unnecessary and introduces potential bugs and maintenance
headaches.  See this message and the rest of its thread for the
