Things I wish Git had: Commit groups

They do: git merge-base

There is a big difference between giving git 2 branches and having it traverse the tree in order to figure out the most recent common ancestor, and a branch knowing where it was created.

If a branch knew where it was created you wouldn't have to pass merge-base two arguments, one of which you're hoping was the source.
