Rogue V4, V5: fix messages when viewing the identified items.
The functions for displaying the list of identified items begin by
prompting for the category of item, using msg(). Rogue V4 left this
prompt on the screen after displaying the discovery list. Rogue V5
erased the message window even if the process of printing the list
created another message which the player had not read.
Messages are now cleared in endline(), which is capable of checking
whether clearing should be done.
