Selling equipment clones the sold item

[HenningKlaskala]

After selling an equipped item, it appears in the shop AND still in the equipment.
Another item disappears from the player's inventory.
To reproduce this, enter shop 3 with just one weapon in your equipment, and just another weapon in your inventory. Then sell the equipment by typing s/a

By repeatedly selling the same good&heavy weapon you can easily make a lot of gold and reduce your weight below zero. :-)

Expected behavior: The sold item should disappear from the equipment.
Tried umoria 5.7.13 (from a Debian archive) and 5.7.15 (compiled on my Debian system).
