      4  * Tests for the options '-lp' and '-nlp'.
      5  *
      6  * The option '-lp' lines up code surrounded by parentheses in continuation
      7  * lines. With '-lp', if a line has a left parenthesis that is not closed on
      8  * that line, continuation lines are lined up to start at the character
      9  * position just after the left parenthesis.
     10  *
     11  * The option '-nlp' indents continuation lines with the continuation
     12  * indentation; see '-ci'.
