Oh, I see...  I was a bit confused about how pipe worked.  Yes, that
makes sense.  Just hook up the STDERR endpoint to a pipe, too, and
you're in business.

For the MSDOS case (with STDERR-to-buffer), we'd just have to open
another temp file, just like we do with STDOUT, so that's a very minor
change.

For the non-MSDOS case, using two pipes and select shouldn't be too
difficult to implement, I think?  Or are there gotchas when using select
in Emacs?

But before embarking on that, I'd like to get some more feedback on the
existing patch.  :-)
