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