	Bulletin command for Fido.

Displays the active bulletin files and lets the caller pick & choose.
Each file number is displayed along with the first non-blank line from
each file. If there are no bulletin files, nothing is displayed.
Bulletin filenames are:

	BULLETIN.001		First (optional) bulletin ...
	...
	BULLETIN.009		... last bulletin

	This repeats until a blank line is entered.
