This is just another patch series in preparation for the rebase--helper.

Relative to v1 of this patch series,

- the grammo fix was backed out because it was picked up separately,

- two new tests were introduced, one demonstrating a bug, the other one
  ensuring that the rebase--helper does not introduce a regression (this
  test actually helped me debug and fix a regression in some previous
  revision of the rebase--helper)

Johannes Schindelin (3):
  t3404: add a test for the --gpg-sign option
  rebase -i: demonstrate a bug with --autosquash
  rebase -i: we allow extra spaces after fixup!/squash!
