We do have 'run_bzr_subprocess' used by tests, but it may not handle
all these cases, and testing may be a bit different.

I guess the correct way depends on digesting all the special cases and
caveats in those bugs and the existing code.  Once we do know the best
way to do it, I would like to get that into a function in bzrlib
itself to avoid unnecessary divergence in future.
