it should be pointed out that the screen libs (ncurses and slang)
optimize away redundant paints (this can be best proved by messing up
the screen (e.g., with write) and doing something that _certainly_ does
a full paint - like opening the editor).
so the redundant painting happens only in the screen lib's frame buffer,
which isn't that expensive, really. so if it's only one line and the
optimization would be pretty complicated, it simply would not pay. but i
can't judge that case, as i didn't read the code.
