From: Elijah Newren <newren@gmail.com>

While at it, the documentation for --root also tried to cover some of
the backend differences between the apply and merge backends in relation
to reapplying cherry picks.  The information:
  * assumed that the apply backend was the default (it isn't anymore)
  * was written before --reapply-cherry-picks became an option
  * was written before the detailed information on backend differences
All of these factors make the sentence under --root about reapplying
cherry picks contradict information that is now available elsewhere in
the manual, and the other references are correct.  So just strike this
sentence.
