This is easily reproducible on a simple test case:

  commit() {
    echo $1 >$1 && git add $1 && git commit -m $1 && git tag $1
  }

  git init repo &&
  cd repo &&
  commit one &&
  commit two &&
  git commit --allow-empty -m empty &&
  commit three &&
  git checkout -b fork one &&
  commit four &&
  git rebase -i fork master
  git --no-pager log --oneline

(this is the same test case I used without "-i" to check the rebase
skipping behavior).

I agree the mention of cherry-pick is a little confusing. I think the
advice to use "git commit --allow-empty" is still the right thing
(although better still would be to recognize that the commit was empty
in the first place and not stop at all). I think the message is showing
the fact that "rebase -i" is cobbled together from other pieces. I
wonder if the sequencer work would make this a little smoother (I
confess I have not paid much attention to what is happening in that
area).
