I can see it being useful, for the reasons Jachym gives; however:

1. It should be optional (although with all of these environment
variables, I'm starting to worry about platforms which have a 4KiB
limit on the combined size of the command line and the environment).

2. It might be better to put it on a line by itself, and only display
it for the first message or warning, so:

	G_message("Hello,");
	G_message("World!");

would produce e.g.:

	* g.module:
	Hello,
	World!

rather than:

	g.module: Hello,
	g.module: World!

This would be preferable in the cases of modules with long names and
modules which are particularly verbose.
