So far only David commented about using ENOENT rather than EREMOTE.

I prefer ENOENT for this case myself and he didn't object when I
explained why, David, any concerns?

Al has been silent so far so either he hasn't seen it or he's ok with
it, Al, any concerns?

And I guess if there are no concerns there's a good chance Andrew is
ok with it for the next merge window, Andrew?

If everyone agrees then we could go ahead immediately so there's a
better chance of getting it into released man pages closer to the
change being merged.
