+ * mail-display.c, mail-format.c: Another big rewrite of this
+ stuff. Now all (well, most) attachments get a small icon with a
+ description and a (non-obvious) right-click pop-up menu with
+ options to save, open in an external program, or show/hide inline.
+
+ TODO: antialias the icon, add more options to the pop-up for
+ certain MIME types, add an icon to the headers, fix PGP to work
+ like everything else, fix message/external-body to work again,
+ add some icon caching action, etc, etc.
