tty ^P recall for dolook/whatis feedback

Noticed while testing the history suppression:  if you have DECgraphics
enabled and look at a graphics character on the map, the topline shows
x      description of x
where 'x' is displayed as it appears on the map (line drawing char).
^P for msg_window:single knows about that and reproduces the effect if
you recall such a line.  But msg_window:full/combination/reverse didn't
know about that and dumped it as-is into text output, ending up with a
strange 8-bit character for 'x' instead of the line drawing one.

I think other rendering schemes will be unaffected by this.  It's just
duplicating what is done for msg_window:single.
