I've seen complaints how looting containers is tedious, and
since multiple containers in the same location are now (and have
been for a while) handled with a menu, the yes-no-quit prompt
for a single container doesn't really mean anything.
Remove that prompt, and remove the "open carefully" message too,
so when you're looting a location with a single container, the
command will drop straight into the loot-in-out -menu. Also
adjust one looting message to explicitly mention the container
if there are other objects on top of it.
Removing the prompt means you can't loot a saddle from a tame
monster with plain loot when standing on a container - you need
to prefix the loot command with 'm' prefix in that case.
