I would say 'always use only run_bzr()'. The others are all just old
things lying around for compatibility. All with slightly different
semantics, but don't actually add anything valuable. (And if you use the
blackbox base, you get 'runbzr()' which splits its argument on whitespace.)

As I've mentioned in the thread, I think it is useful for sftp, though
maybe it would be better to collapse to a group of start+length pairs,
rather than start+end pairs.
