I fixed that on Friday already, in a slightly different manner. Do you
see a problem with that approach?

I've made public the version I'm working on. That's the version I'm
ultimately going to commit. It would be a lot more helpful if you
provided these patches over that version. Otherwise I have to refactor
them over that codebase, possibly introducing new bugs.
