Since b10ac50 (Fix pulling into the same branch., 2005-08-25), git-pull,
upon detecting that git-fetch updated the current head, will
fast-forward the working tree to the updated head commit.
Implement tests to ensure that the fast-forward occurs in such a case,
as well as to ensure that the user-friendly advice is printed upon
failure.

* Added git rev-parse checks to make it explicit that the branch head has
been updated.
* "git checkout -b third second^" to make it explicit we are fast-forwarding.
