By the way, new git-describe gives us also number of commits since
tag, and it would be nice to have number of commits since init...
but that can be easily obtained using "git rev-list $1 | wc -l".

I guess that some use git-describe with --abbrev=0 to get closest
preceding tag: getting INIT would confuse them.

That said, we could use e.g. INITg2a45ba+10-g4ee2ab
