rhack() normally calls parse(), parse() sets context.move to True
assuming that the player's next action will take game time, then
when it returns, rhack() sets context.move back to False if the
assumption turned out to be incorrect. But when performing actions
after picking something in inventory, rhack() doesn't call parse()
so context.move is left at False.
This was hidden by making the inventory command take game time if
the player picked an item and set up an action to be done with it
even though the action hadn't taken place yet. So time was being
accounted for but if the hero didn't get consecutive moves then
monsters got their turn between the shouldn't-take-time inventory
command and the ought-to-behave-like-normal-command queued action.
My initial attempt to fix this (before figuring out how context.move
works) by stopping inventory from taking time didn't work because
queued item-actions stopped taking time too, or rather the fact that
they took no time became exposed. This second attempt doesn't have
that problem and I think it is correct.
