Comment(by martinl):

 Replying to [comment:20 glynn]:

 > If MONITOR is set, it names a program which will be executed with the
 complete argument list of the original program (including `argv[0]`). So
 e.g. if MONITOR is set to "wx-monitor", then running "d.rast
 elevation.dem" would execute "wx-monitor d.rast elevation.dem" then
 terminate (or would execute it using execve(), which has essentially the
 same result).

 I have implemented that in r64401 and document it in r64403. BTW, now we
 could remove D_save_command() from trunk which is after this modifications
 empty, any objections? Currently it's working only for file-based monitors
 (cairo, png), implementation for wxGUI monitors is in progress.

 I have update `d.mon` which writes currently only one variable, ie.
 `MONITOR`. Support files including python renderer are stored in .tmp dir.
 Also `d.erase` and `d.redraw` have been updated to the new architecture.

 Testing welcomed.
