An idea for the "Leftover Bits": rebase -x to imply -i

Hi Junio,

here is an additional ideas for the "Leftover Bits" on git-blame.blogspot.com (Is there another way of contributing these, such as sending a patch against some repository? Or any other way which may bother you less?)

* "rebase -exec" requiries to be an explicit interactive rebase (i.e.
--interactive was given)
  Could --exec just imply --interactive with a no-op editor? If so
write a patch for it;
  if not, document the reason in the man page at the --exec option.

Thanks, Stefan
