Accidentally, I got error message which lead me to partial fix in r63306.

After running `d.mon cairo` in terminal, I get in wxGUI

Details: MONITOR variable defined, GRASS_RENDER_IMMEDIATE ignored

I guess that any of MONITOR in GRASS GIS environmental file and
GRASS_RENDER_IMMEDIATE is sufficient for running d.* commands. I think the
modules before r63227 which had the monitor check are not meant to run from
wxGUI directly; at least some of them are caught by GUI and executed
differently.

I think that the behavior I got in wxGUI might be a bug since nothing was
rendered but I don't understand what are the valid states of all variables.
