I think this should say something along the lines of "if the response
body is rendered by an interactive user agent then the response body
could be a hypertext document containing a link so users of old clients
that do not support the status code as specified can easily follow the
redirect". I think the "unless HEAD" is too broad since it would apply
to cases where the hypertext document would be of no use (like for an
OPTIONS response) and this is not required for interoperation among im-
plementations and does not deal with "harm", so the use of RFC 2119
"SHOULD" is wrong.
