/*
 * Tests for the options '-lpl' and '-nlpl'.
 *
 * The option '-lpl' lines up code surrounded by parentheses in continuation
 * lines, even if it would extend past the right margin.
 *
 * The option '-nlpl' moves continuation lines that would stick over the right
 * margin to the left, to keep them within the margin, as long as that does
 * not require placing them to the left of the prevailing indentation level.
 *
 * These switches have no effect if '-nlp' is selected.
