Fixes#202
When swallowed, you can take things from the engulfer's inventory, if
there are any, via pickup. Items might be worn by the engulfer and
when "picked up" those weren't being unworn before being added to
hero's inventory. Then they would be formatted as "(being worn)" and
could trigger warnings or worse.
Conceptually they should be worn on the outside and not be accessible
from the inside, so I've made attempts to pick up worn items fail
rather than fix up the unwearing.
Using ':' when swallowed to look at the engulfer's inventory describes
that inventory as "contents of <mon>'s stomach". That's weird for any
worn items, but the situation is so rare I haven't made any attempt to
deal with it.
