A container is either owned by the hero, or already
owned by the shk (!ltmp), or the shk isn't interested
in buying it (also !ltmp). It's either empty (!cltmp)
or it has contents owned by the hero or it has some
contents owned by the hero and others by the shk.
(The case where it has contents already entirely owned
by the shk is treated the same was if it were empty
since the hero isn't selling any of those contents.)
Your container and shk is willing to buy it:
"... your <empty bag>. Sell it?"
"... your <bag> and its contents. Sell them?"
"... your <bag> and item inside. Sell them?"
"... your <bag> and items inside. Sell them?"
Your container but shk only cares about the contents:
"... your item in your <bag>. Sell it?"
"... your items in your <bag>. Sell them?"
Shk's container:
"... your item in the <bag>. Sell it?"
"... your items in the <bag>. Sell them?"
FIXME:
"your items" should sometimes be "some of your items"
(when container has some stuff the shk is willing to buy
and other stuff he or she doesn't care about); likewise,
"your item" should sometimes be "one of your items".
That would make the prompting even more verbose so
living without it might be a good thing.
FIXME too:
when container's contents are unknown, plural "items"
should be used to not give away information.

* The caller is about to make obj_absorbed go away.

* There's no way for you (or a shopkeeper) to prevent globs
* from merging with each other on the floor due to the
* inherent nature of globs so it irretrievably becomes part
* of the floor glob mass. When one glob is absorbed by another
* glob, the two become indistinguishable and the remaining
* glob object grows in mass, the product of both.
*
* billing admin, player compensation, shopkeeper compensation
* all need to be considered.
*
* Any original billed item is lost to the absorption so the
* original billed amount for the object being absorbed must
* get added to the cost owing for the absorber, and the
* separate cost for the object being absorbed goes away.
*
* There are four scenarios to deal with:
* 1. shop_owned glob merging into shop_owned glob
* 2. player_owned glob merging into shop_owned glob
* 3. shop_owned glob merging into player_owned glob
* 4. player_owned glob merging into player_owned glob
