[PATCH 0/4] rebase -i: fix ORIG_HEAD handling

The buffer containing the oid for ORIG_HEAD is overwritten before ORIG_HEAD is created. This series fixes that bug and then converts the code to use struct object_id rather than passing around strings.

Thanks to Caspar for reporting the bug and providing a reproducible example

Phillip Wood (4):
  rebase -i: stop overwriting ORIG_HEAD buffer
  rebase -i: use struct object_id rather than looking up commit
  rebase -i: use struct object_id when writing state
  rebase -i: simplify get_revision_ranges()
