Adds a NOMORE hook to TinyFugue that is triggered when a user catches
up with backscroll and is no longer backlogged (i.e., the works is no longer
paused and "More" is no longer displayed in the status bar).

Useful when combined with tf-notifier's
(http://horde.net/~jwm/software/misc/tf-notifier) 'backlogged' notification
limitation.
