Well, it's all the same algorithm, where just the bit usage differs. 
git-rev-tree is slightly closer, if only because the original 
git-merge-base only did two heads, if I recall correctly (while 
git-rev-tree did 16 - the ability of git-show-branch to do 29 came from 
just using all the free bits rather than the high bits like rev-tree did)

Yeah, I don't think there is any reason to really support it. If you have 
more than a few heads, you really do need the graphical version to see 
what is going on, and git-show-branch doesn't buy you anything.
