commit cbe8642e2ade47ddfc768921db54221a67f4faa9
Author: Tomas Popela <tpopela redhat com>
Date: Fri Feb 21 22:53:36 2014 +0100
Rework the way how the HTML messages are converted to plain text
Also now the user is asked whether he wants to lose the formatting of
message when he is replying on HTML message or editting message as new
and he doesn't have the "Format messages in HTML" option set.
