I agree with refactoring along the way, but I think it's important to clearly state the _purpose_ of a branch or pull request, and to make sure that refacors don't wildly blow out the scope of the PR. I've been on the receiving end of too many PRs that refactor a bunch of things all at once because "well I was in there" to feel good about unchecked scope creep in PRs.
