Well, I just fixed the ones in make_outputdirs because it seemed weird
that that part of the function was not doing something the earlier parts
did. I didn't look around for more trouble.
I think that pg_fatal'ing on the grounds of path-too-long once we've
already started the upgrade isn't all that great. Really we want to
fail on that early on --- so coding make_outputdirs like this is
fine, but maybe we need a different plan for files made later.
