[PATCH v2 0/3] rebase -i (reword): call the commit-msg hook again

It is actually not only the commit-msg, but also the prepare-commit-msg hook...

Changes since v1:

- changed `int flags` to `unsigned int flags`

- uncuddled the if...else if... construct to not mix the "goto leave"
  logic with the one adding the VERIFY_MSG flag

Johannes Schindelin (3):
  t7504: document regression: reword no longer calls commit-msg
  sequencer: make commit options more extensible
  sequencer: allow the commit-msg hooks to run during a `reword`
