The getobj prompt for charging was presenting any chargeable tool in the hero's inventory as a suggested charging target, even tools which were unidentified and undistinguishable from their mundane counterparts (e.g. bag of tricks, magic harp, horn of plenty...). This leaked information about the identity of these items and made it possible to determine whether a generic 'harp' was magic or not. When suggesting chargeable tools, include only those which are actually known to be chargeable (unidentified or unseen chargeable tools can still be selected, they just won't be suggested targets). Basically the same as what's done for a potion of oil in the apply prompt.
