[PATCH v3 0/4] rebase: teach rebase --keep-base

Thanks again for your feedback, Ævar! I think we're both on the same page now. Hopefully I've addressed all of your high-level concerns with this patchset and we can move into a discussion on implementation detail.

This patchset now depends "[PATCH 1/8] tests (rebase): spell out the `--keep-empty` option" which is the first patch of Johannes's "Do not use abbreviated options in tests" patchset[1]. (Thanks for catching that, Johannes!)

Changes since v1:

* Squashed old set into one patch
* Fixed indentation style and dangling else
* Added more documentation after discussion with Ævar

Changes since v2:

* Add testing for rebase --fork-point behaviour
* Add testing for rebase fast-forward behaviour
* Make rebase --onto fast-forward in more cases
* Update documentation to include use-case
