Glynn:
[stderr is unbuffered, stdout is buffered]

Thanks for correcting me. This opens more G_message() options.

I agree. But I'd replace "fixed rules" with "[strongly] recommended
guidelines" and expand it to cover lots of consistency issues which the
SUBMITTING files don't cover. IMO hard rules have a bad tendency to
incorrectly force a grey question into a black or white answer, and
shift a debate from practical solutions to rhetorical bickering.

I agree. Although I'm not sure what GRASS_MESSAGE_FORMAT does.
