I agree.  I will leave that decision to the more experienced git
developers.  I'm happy to work either way.

Right.  That's the approach I've taken for now but it's easy to switch.
There aren't that many changes.

Done.

Done.

I have a patch that does all of the above but it is one monolithic blob.
Like I said, the changes aren't extensive so it's easy for me to change
strategies.

Ok, that sounds fine to me.  I'll do that in a private branch.  What
should I send as patches to the mailing list?  I'm assuming we don't
want [PATCH 235/12342], etc. sent to the list chronicling the entire
history.  :)

Heh.  I thought about that too.  :)

Yeah, I agree.
