If you want ff2 and ff3 to appear as separate merges in the history,
then you merge them separately.  But they can all sit in the same
feature branch at your end.

In my context, I often want to review the contributions that our
people send in (via Bazaar branches on Launchpad).  There I prefer if
they do all their work of a particular feature in a single branch.
Then I can just pull it into my local copy, review it and merge it in.
If they make a new branch for each fix, it will add additional set-up
cost for me to make a copy of their branch.

I might also mention that it was in this context that I first used
rebase.  Since the contributions are often based on some old revision
in the trunk, which is a pain to go back to, I first rebase my copy of
their branch to the current state of the trunk.  Then I review and
test each commit, before merging it in.  I think this is a great
application of rebase.  Not only is it safe (because rebase is done
before review), it is a lot better than merge which will just plonk
everything together and hope for the best!

Sounds perfect!
