Frankly, I've never understood the 'g' prefix at all. I don't use
git-describe much, but some people have sent me things with this 'g'
on the front and every time I've received that I was annoyed to find
the commit identifier they sent didn't work until I manually removed
it.

It's definitely never provided any useful semantic information to me.
