that will also mask any real warning and error messages, which isn't so
nice. Makes debugging + support much harder.

G_message() or G_warning()?

if just G_message(), d.font could run  G_putenv("GRASS_VERBOSE","0"); to
disable all uninteresting messages and % done but still keep G_warning()
and G_fatal_error()s.

I think
will do the same as 
  G_set_verbose( G_verbose_min() );

? So better to use the latter ? Will level set with G_set_verbose()
reset when the module exits, or will it be persistent within libgis?
In that case, the former is preferred and the latter should be avoided
for general use by modules.
