One bug or multiple bugs probably doesn't matter that much IMO, but in
general, I prefer to be more granular, as it makes distributing tasks
accross multiple people, and tracking progress easier.

So +1 for separate bugs, particularly if Clint has already started that

In general, split the changes into the smallest logically related chunks,
but don't artificially split it into one or two files per commit, if e.g the
change is really that you sedded all the tests to s/assertFoo/assertBar,
just commit all the changes related to the sedding in one commit.

One file per patch is not a good idea IMO, I think the review burden is
minimised if you make sure that each commit just contains the exact same
change to many files, then it's quick to click through them all and confirm
all looks OK.
