Yep, that's what I think, too.  My advice is to always use the
"master" branch of my tree as the base.  I use a lot of topic
branches, and they are almost always based on my "master".

There will be exceptions where that doesn't work because your patch
depends on something already in my tree or something in another tree.
But those are actually fairly rare, so just point that out in your
cover letter and we'll sort it out on a case-by-case basis.
