There is a bug in larn that was carried over into Ularn which allows
one to sell a gem an unlimited number of times.  To reproduce this
bug, follw these simple steps:

	1. Enter the bank with one or more gems in your possesion
	2. Note the inventory letter of each gem
	3. Exit the bank
	4. drop all your gems
	5. Enter the bank -- notice that no gems are listed by the bank
	   that you can sell.
	6. Sell them anyway (using the same inventory letters that you
	   wrote down in step 2).
	7. Exit the bank
	8. pick up the gems
	9. repeat steps 1-8 until you have enough money to buy the lance
	   of death (or whatever else you need).

Following is a fix for this bug.  It is a patch that should be applied
to store.c -- this patch works for larn as well as Ularn.
