So, back on d.area:

I have added in src/includes/colors.h
#define MAX_COLOR_LEN 32 /* max length of color string */
#define MAX_COLOR_NUM 13 /* number of coded colors */

and implemented the background color filter for "d.area -f" mode.
Now all areas are filled when using -f, but the monitor background
color is omitted. The prevents confusion as otherwise areas filled
with monitor background color seemed to be non-existing.

Let me know if problems occur,

cheers
