I haven't been active in the past decade, but here's a small patch. Main

branch only.  This adds a check when setting a new fruit so that if no fruits
have been created since the last time the option has been set, the current
fruit is overwritten.  Result: the user cannot repeatedly set the fruit
option and overflow the maximum fruit number.
