The end of game disclosure for inventory was passing want_reply==True
to the inventory display routine. I don't know why because you can't
select anything. This resulted in Qt disclosure showing inventory
with the [Ok] button disabled and blank boxes instead of object
glyphs beside the inv letters. Changing to want_reply==False fixes
both aspects of that.
It has no apparent effect on tty or curses; on X11 (where [Ok] was
already enabled) it disables the [Search] button, a plus. I don't
know whether it might mess up final disclosure for inventory on
WindowsGUI. Or whether any interface which uses perm_invent window
for final inventory disclosure (if there are any) will be adversely
affected.
