Ah, indeed you are right.  Let's drop this patch then.

However, we have a bigger problem with empty commits, in that there
are really three modes rather than two:
  * Automatically drop empty commits (default for am-based rebase)
  * Automatically keep empty commits (as done with --keep-empty)
  * Halt the rebase and tell the user how to specify if they want to
keep it (default for interactive rebases)

Currently, only the first option is available to am-based rebases, and
only the second two options are available to interactive-based
rebases.  But if we want to make all three available to
interactive-based rebases, what should the command line option look
like?  --empty={drop,ask,keep}?

(And deprecate but continue to support --[no-]keep-empty?)

And should the two rebase modes really have a different default?  What
should the default be?
