The names might not be great, but since --no-keep-empty and --keep-empty already existed for years and prior to 2.16 and were about how to handle commits which started empty, it seemed reasonable to (re)use them. My personal preference would be that for commits whose keep/drop state can be determined solely by looking at its contents of the commit before the rebase (whether that's because they start empty or for whatever other reasons), I'd rather recommend that people just fire up an interactive rebase and pick out the commits they don't want to keep. So, my own bias would be that I wouldn't recommend that new people use either --keep-empty or --no-keep-empty. In my mind, the --[no-]keep-empty flags are just for backward compatibility, so going through effort to rename or alias doesn't seem like it makes a lot of sense. I don't have a strongly held position here and I'm happy to hear alternate viewpoints, but that's the thought process I went through when creating this change. > > +--no-keep-empty:: > > --keep-empty:: > > + Do not keep commits that start empty before the rebase > > + (i.e. that do not change anything from its parent) in the > > + result.

I guess I should technically probably wait until I create a commit on top of that series and this one to mention it. Or rebase Jonathan's commit, and combine the two series (adding his second since mine might be viewed as a bugfix).
