Yes, something like that (modulo the long line).

My refactoring won't affect the files and directory much, so you can proceed 
similar to that patch without conflicting. An appropriate branch like that 
could be committed before my refactoring, depending on when it is ready. 

My refactoring will only remove the `->GetMakefile()` part from affected 
lines, but it will take a while to get to the point where that can actually 
be done, so you don't need to wait for it.

Thanks,

Steve.
