+ <p>As from Erlang/OTP 21.0, a field width of value
+ <c>0</c> can be used for specifying that a line is
+ infinitely long, which means that no line breaks
+ are inserted. For example:</p>
+
+ <pre>
+5> <input>io:fwrite("~0p~n", [lists:seq(1, 30)]).</input>
+[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30]
+ok</pre>
+
<p>When the modifier <c>l</c> is specified, no detection of
printable character lists takes place, for example:</p>
<pre>
-5> <input>S = [{a,"a"}, {b, "b"}].</input>
-6> <input>io:fwrite("~15p~n", [S]).</input>
+6> <input>S = [{a,"a"}, {b, "b"}],
+ io:fwrite("~15p~n", [S]).</input>
