Hi,
I added G_important_message() which will do G_message() when
GRASS_VERBOSE=1. Usually just G_percent() or G_clicker() would be
printed at that verbosity level.
To test try "g.message -i". Use sparingly.
I also added some ideas+opinions to the message standardization wiki
page:

(make distclean)
