Well, I don't think it needs to be some hard "exactly 12". At some
point in the future, you *will* get collisions (Konstantin already
created a tree for that exact thing) and git will automatically give
you 13 or more characters.
But I also don't want to encourage people for no good reason to go
overboard, and we end up with extra line noise, and commit ID's that
don't line up nicely etc. The whole "12 characters isn't enough" isn't
actually the real and present problem we have (and there was a whole
long discussion about the things that _are_ problems).
