Merge branch 'mz/cherry-pick-cmdline-order'

"git cherry-pick A C B" used to replay changes in A and then B and
then C if these three commits had committer timestamps in that
order, which is not what the user who said "A C B" naturally expects.

* mz/cherry-pick-cmdline-order:
  cherry-pick/revert: respect order of revisions to pick
  demonstrate broken 'git cherry-pick three one two'
  teach log --no-walk=unsorted, which avoids sorting
