[pan2: 16/23] Add wrap selected to post editor.

[Petr Kovář <pmkovar src gnome org>]

commit c657736c81adfb53bcae549c6ffe3a048ec7dae8
Author: K. Haley <haleykd users sf net>
Date:   Thu Aug 5 17:31:48 2010 -0600

    Add wrap selected to post editor.
    
    When creating a reply the wrap mode now determines if the original
    message is wrapped before being placed into the edit window.  Also
    a new edit entry has been added, 'Wrap selected', which uses pans
    wrapping method on the selected text so it also works on quoted
    text.
