Comment 56 for bug 334809

Patch for xchat-gnome to use append.

Question though for notify-osd developers: Is there any scenario where appending ISN'T the right behavior? Is it a common case?

Since the normal behavior of upstream's notification-daemon is to add another notification for each notification, it seems that appending as the default would be the closest to "normal" behavior. In the odd case where one wouldn't want append, maybe an opt-out hint ("x-canonical-no-append"?) could be specified.
