anmesia of last discovery (trunk only)

     While testing something, I noticed that my last remaining discovery
would never be forgotten.  The formula
  count = ((count * percent) + 50) / 100
always yields 0 with count==1 and percent==25 (the value used for mind
flayer attacks).  Not likely to come up in actual play very often....
