This is a patch to make Pine 3.94 honor IMAP4 subscription lists.
Specifically:

	- A #define MBOX_SUBSCRIBE is added to the top of pine.h.
	- If MBOX_SUBSCRIBE is defined, a new feature in the feature-list
	  is added, "use-subscriptions"; when set, Pine only looks at
	  subscribed folders in folder collections; when unset, it looks
	  at all of them.
	- Version number is changed from 3.94 to 3.94L.

The patch makes a few changes in folder.c; a few others are in pine.h,
init.c (for the feature-list switch), other.c and pine.h (for the help
file), and maybe some other places.

This patch was originally written by Jeff Hutzelman and has been modified
slightly since then by Derrick Brashear and myself.
