Well, there you go, never knew about that. And, except for the name, and
the fact that it gets whitespace correct, it's identical to my stderr.

I think my name is better, but open to differences of opinion.

So, options:

1) drop my patch
2) accept my patch, make external-debbugging-output use stderr (or vice
versa), to keep the name alive.

Don't really mind. I have no use case that differentiates between stderr
and stdout.
