is there a way to reference the branch point?

If I make a branch `foo' off master, commit a bunch of times, is there
a way to reference the place on master from which I branched?

Thanks.

Depends, if you make a new branch from master, you can use 'git merge-base', so:

$ # on master
$ git checkout -b foo-topic-branch
$ # work work
$ git commit
$ # work work
$ git commit

Now you want to know where you branches off from master:

$ git merge-base foo-topic-branch master

That will show you the commit you branches off from, even if master
has grown new commits since then.

That works, but what if I don't know it's off master?  Normally, a
human would, but what if this is a script I'm writing?

Thanks.
