Thanks for the explanation. This looks fine to me, though I would feel better if someone else gave it a look too.

extra semicolons

That sounds like a good idea. When you do that, could you please refer to the llvm raw_ostream classes to see how they handle this. Long term, it would be great if we could replace lldb's classes with those, so I'd like to avoid diverging from them if possible.
