Teach git-describe to display distances from tags.

Browse source 
If you get two different describes at different
times from a non-rewinding branch and they both come up with the same
tag name, you can tell which is the 'newer' one by distance.  This is
rather common in practice, so its incredibly useful.

[jc: still needs documentation and fixups when traversal gives up
 early.]
