Indeed.  This was a mistake.  A long time ago we intended to implement
this flag, but it was never integrated.  I think I typo'ed the options
string in the zfs command; and then when writing the manpage I
remembered that long-lost implementation.

In any case, we should remove the documentation of the "zfs send -r"
flag, as that flag doesn't actually exist.
