rcp -r is broken in 4.7 and 4.8. A fix is included below. The
web-based bug interface is currently disabled so I can't open a bug
report. I believe the person that provided the patch to me also
indicated the problem exists in 5.0, but I'm unable to verify that
since I'm only running 4.x. I think they monitor this list so I'll
let them speak up if they choose to.
