If you're trying to get your changes into the master repository, that
would be a requirement.  Splitting it up into independent changes
would help us review them - send the smallest and most likely to be
approved first, so we can reduce the divergence until we get a chance
to work through the more complicated ones.

I don't think seeing all your local changelog entries is the right
thing for us, though (my previous confusion is evidence of this ;).
Please write changelog entries that are appropriate for the patches
we'll be seeing.
