Repeat last command (') key is a godsend for grindy situations, however, sometimes one needs to look around, check stats/inventory, see items on the ground, etc to know whether the action should be continued. Currently it requires restarting the process. (E.g. finding a writing set in the inventory, finding a blessed blank scroll, typing in "scroll of corruption removal").

It would be nice if only actions that take a turn were repeatable.
