From c44ce805de8ca01a5ceaa8db94a347e7236f17ce Mon Sep 17 00:00:00 2001 From: David Edmondson Date: Wed, 17 Feb 2010 10:51:51 +0000 Subject: [PATCH] notmuch.el: Allow citation suffixes to be shown as well as prefixes. In many conversations the last few lines of a citation are more interesting than the first few lines, hence allow those to be shown if desired.
