2164    a @samp{.ll @var{length}} request to initialize the line length, prior
2165    to use of the @samp{TH} macro, is supported for backward compatibility
2166    with some versions of the @code{man} program.  @emph{Always} use the
2167    @option{-rLL=@var{length}} option, or an equivalent @samp{.nr LL @var{length}}

2169    In particular, note that in nroff mode, the request @samp{.ll 65n},
2170    (with any @var{length} expression which evaluates equal to 65@dmn{n},
2171    i.e., the formatter's default line length in nroff mode), will @emph{not}
2172    set the line length to 65@dmn{n} (it will be adjusted to the @code{man}
2173    macro package's default setting of 78@dmn{n}), whereas the use of the
2174    @option{-rLL=65n} option, or the @samp{.nr LL 65n}
2175    request @emph{will} establish a line length of 65@dmn{n}.}
