[GSoC][PATCH v6 0/5] Teach cherry-pick/revert to skip commits

I've covered the advice message behind `advice_resolve_conflict` variable and changed the order of error and advice to match that of 1/5. I believe that we don't have any advice variable appropriate for advice in 1/5.

Rohit Ashiwal (5):
  sequencer: add advice for revert
  sequencer: rename reset_for_rollback to reset_merge
  sequencer: use argv_array in reset_merge
  cherry-pick/revert: add --skip option
  cherry-pick/revert: advise using --skip
