Yes, feature, selected region has priority and scale is calculated to fit 
the page.

ps.map.barscale script exists, but I have not tested.
I use EPS file created in some other graphic program. 
(you can use negative values for position in ps.map => outside region)

We need some library for basic symbols (sites), barescales, north arrows, ...
Anybody has some free collection in EPS (or convertable to EPS)
or knows about some free library on web? 
Grass users/contributors are invited to start some library of symbols 
which could be  distributed with grass later.
