Noticed while testing statuslines on a small terminal window. Using
the cursor to pick locations that panned the map to view a new subset
would end up showing a new view of the regular map rather than a
different section of what was currently displayed. For farlook that
caused monsters to take on new hallucinatory forms which was fairly
inconsequential, but for #terrain and various forms of detection it
reverted to the ordinary map instead of showing the map features that
the player requested or the temporarily revealed monsters and such.
Most interfaces keep track of the whole map and just show their view
of the new subset when panning, similar to redisplay after being
covered up and then re-exposed, but tty isn't doing that. I made
same change to Amiga as to tty since the code it was using was very
similar. I haven't touched any of the other interfaces and assume
that they don't need this. I've verified that curses and X11 don't.
