it's not an oddity in netbsd.  it's an oddity in freebsd.  currently:

	the use of flags on netbsd causes rm to fail
	the use of flags on openbsd causes rm to fail
	the use of flags on bsdi causes rm to fail
	the use of flags on macosx causes rm to fail
	the use of flags on freebsd DOES NOT cause rm to fail

perhaps the error that rm prints in such a case should give a hint as
to the *why* of the failure, but removing files when flags have been
set specifically to avoid such an event is, imho, wrong.
