Fashionably late, of course. I agree with your reasoning that it is
a more sane default. The only thing that would make me hesitate on it
now is that it is a behavior change. I suspect the group we would be
breaking is small or even zero, though.

Well, I have to admit that I'm a _tiny_ bit nervous that some odd OS or
filesystem has special magic st_dev rules so that it changes randomly even
within a filesystem, but that would be very non-posix (think of the
confusion it would cause standard UNIX tools like 'find -xdev' etc), so
it's more a worry of "I have no idea what st_dev means on Windows" than
anything really solid.

st_dev means "Drive number of the disk containing the file (same as
st_rdev)."[1], and mounting file systems as subdirs of other file
systems is rare (but possible) on Windows.

However, in our (f)stat implementation, st_dev means 0 -- but this
might be possible to improve on.
