Removing the option is best for humans.

-r is the same as -R under Linux (linux_base_8), and it isn't even deprecated
in cp --help at least, so it won't go away, and fingers will be trained to
use it in preference to -R, for at least another 20 years.

This reminds me that I rarely actually use cp -R, since it is too broken
to use -- it snaps hard links, unlike Linux cp.
