154    Note that the use of a `.ll' request to initialize the line length
155    is supported for backward compatibility with some versions of the
156    .B man
157    program;
158    direct initialization of the `LL' register should
159    .I always
160    be preferred to the use of such a request.
161    In particular, note that a `.ll\ 65n' request will
162    .I not
163    preserve the normal
