Heya,

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.
