[PATCH v3 0/3] automatically skip away from broken commits

This patch series makes "git bisect skip" skip away from an area where the commits cannot be tested.

This is done automatically. The user has nothing todo. We alternatively try to test commits 20%, 40% and 60% away from the optimal commit that has been skipped.

Some comments have been added and a left over from v1 has been removed since v2, thanks to Junio.

  bisect: add parameters to "filter_skipped"
  bisect: when skipping, choose a commit away from a skipped commit
  t6030: test skipping away from an already skipped commit
