 Replying to [comment:11 glynn]:

 > It's bogus because there's simply no reason for that check to be there.
 Everything worked fine before someone mistakenly added it, and works fine
 now that it has been removed. The only consequence of that check was to
 generate an error for entirely valid usage.

 well, it worked fine also before you reverted it. The reason of this
 condition was simple. Not to generate output by the default display driver
 (ie. to write map.png to the current directory) without noticing to the
 user. Such behaviour is really obscure. The user should be asked to start
 monitor (`d.mon`) or to specify display driver by environmental variable
 (GRASS_RENDER_IMMEDIATE).
