showed non-empty containers in inventory (including the one being
applied) with a 'for sale' suffix during put-in operations, as if the
shop was trying to sell it to the hero. Amount shown was cumulative
value of its contents. (Using /menustyle:T doesn't show the container
being applied so this wasn't visible with it unless other non-empty
containers were being carried.)
Two or three fix attempts solved one problem but introduced another.
This one seems to finally get things right but considering that there
was trial and error along the way, my confidence isn't great.
