It might be useful to have an additional log level to notify users of correct
behavious instead of leaving them in the dark. I tried adding it without
breaking
ABI or deprecation warnings. Also added an example that will be split in a
separate patch when after a decision is taken.
I picked the color of light (bold) green, works in unix terminals, but can
anyone double check on windows?
Thoughts, ideas?
