term.h #defines lines, pad_char and no_color_video macros which conflict
with existing curses code. We change lines to alines and nlines depending
on use, pad_char to padchar and no_color_video becomes no_color_attributes
but with a strong alias from no_color_video.
each line that we copy.
We also need to touch the destination window here.
Fixes display bug in atc(6). Bug reported by and fix tested by
David Holland.
copywin() couldn't seem to decide whether it should work in window or
screen coordinates - and managed to do neither.
Change copywin() to use window relative coords (as ncurses and solaris do),
and change overwrite() and overlay() to use the modified interface.
It is now possible to use overwrite() to save part of curscr while a
temporary window is drawn.
