curses map window

tty ignores map column #0 (0-based index), like the core, and draws
the map in screen columns 1 (1-based index) through 79, leaving screen
column 80 blank.  curses was drawing all 80 map columns and since #0
was always unused, screen column 1 was blank and the map was shown in
2 through 80.  Change curses to work like tty.

This was too easy; there may be problems lurking.  One known issue: it
should be made smarter about when clipping/panning is necessary since
it thinks that a full 80 columns are needed but 79 suffice.
