Of course. That's the simple and more obvious fix for the recent g.region 
issues. I've updated gui/tcltk/gis.m/mapcanvas.tcl (after Michael's fixes 
last night) to just discard stderr after all those g.region calls instead 
of merging it with stdout. So the calls to g.region should be tripley 
robust now (catch, discarding stderr, and checking the output lines match 
a regexp).
