From: Johannes Schindelin <johannes.schindelin@gmx.de>
The step to prepare a pre-rebase commit history is _identical_ in _all_ of the test cases (except of course the `setup` case). It should therefore clearly a part of the `setup` test case instead.
As the `git filter-branch` command is quite costly on platforms where Unix shell scripting is simply slow (meaning: on Windows), this shaves off a noticeable part of the runtime: in this developer's setup, the time was reduced from ~1m25s to ~1m.
