r.combine

[Darrell McCauley]

The man page says:

     layers.  After the r.combine program is started, the users
     are asked if they want the graphic output to go to a color
     graphics monitor.  If a color graphics monitor is not used,
     the graphic output is displayed on the terminal screen.

but this is not the case.
also, there seems to be some unfinished code in init_comb.c

    s->answer = 0;

    use_graphics = !s->answer;

(thus use_graphics is *always* true).

it seems like a thought was started but never finished.
Has anyone fixed this? We have a user who would like to work
over a serial line (no graphics monitor). I've hacked
something for him but I hate to convolute my deparment's
grass bin with hacks.
