[PATCH 0/2] finding the fork point from reflog entries

The first one is a clean-up of the code to parse command line
options to "git merge-base".  Options such as "--independent",
"--is-ancestor" and "--octopus" are mutually exclusive and it is
better expressed in terms of the recently introduced OPT_CMDMODE.

The second one implements the entire logic of the for loop we see in
"git pull --rebase" directly using get_merge_bases_many() and
postprocessing the result.

Junio C Hamano (2):
  merge-base: use OPT_CMDMODE and clarify the command line parsing
  merge-base: "--reflog" mode finds fork point from reflog entries
