[PATCH v2 0/3] rebase -i: mark commits that begin empty in todo editor

Changes since v1:

 * Resurrect --no-keep-empty (for commits which begin empty), which can be
   used orthogonally to --empty (for commits which become empty). Docs
   updated as well
 * Add a commit improving the error message for --apply being used with
   non-apply arguments

I wanted to base this commit on jt/rebase-allow-duplicate, in particular to add a patch moving his new --[no-]keep-cherry-picks arguments to be close to the --empty={drop,keep,ask} and --[no-]keep-empty flags, since all three are related. But unfortunately that series was based on 2.25, and my series needs to be based on 2.26. So, for now, I'm just keeping the two series independent and will submit a fixup patch after these two are both merged down to move all the arguments near each other.
