[PATCH v4 0/5] cleanup ra/rebase-i-more-options

From: Phillip Wood <phillip.wood@dunelm.org.uk>

Thanks to Danh for the review, I've updated the tests accordingly.

Phillip Wood (2):
  rebase -i: support --committer-date-is-author-date
  rebase -i: support --ignore-date

Rohit Ashiwal (3):
  rebase -i: add --ignore-whitespace flag
  sequencer: rename amend_author to author_to_free
  rebase: add --reset-author-date
