While this behaviour is non-intuitive, it has existed in UNIX going back
to at least 1984. I've seen it in BSD and SVR[0123] systems, and I
suspect the kernel has behaved this way since the beginning. Because of
this legacy I don't think this can be called a bug, and therefore this
PR should be closed.
It might be worth adding a note to mount(2), though.
