This part makes sense, but ...

... as I already pointed out, this does not seem to belong to the
change.
What makes this hunk necessary?
We used to use run_merge() to fast-forward, now we let run_rebase()
to first "checkout" their tip, which ends up to be a fast-forward in
the "can_ff" situation. As a side effect, opt_ff gets contaminated
with the current code, but that would not affect what happens after
this part (i.e. call to rebase_submodules()).
