1047    Additionally, you may express a new line length relative to the
1048    current line length by prepending a plus or minus sign to the
1049    argument.  Thus, if you wanted to increase the line length by 3
1050    <a href="definitions.html#TERMS_PICASPOINTS">points</a>, you could
1051    do
1052    <p>
1053    <pre>
1054            .LL +3p

1060    escape as the argument to <strong>LL</strong>, like this:
1061    <p>
1062    <pre>
1063            .LL +\w'.'u
1064    </pre>

1066    The above example increases the current line length by the width of
1067    a period.  Notice that you must append the
1068    <a href="definitions.html#TERMS_UNITOFMEASURE">unit of measure</a>,
1069    <strong>u</strong>, to the escape since .LL requires a unit of
1070    measure.
