5 * Tests for the options '-lpl' and '-nlpl'.
6 *
7 * The option '-lpl' lines up code surrounded by parentheses in continuation
8 * lines, even if it would extend past the right margin.
9 *
10 * The option '-nlpl' moves continuation lines that would stick over the right
11 * margin to the left, to keep them within the margin, as long as that does
12 * not require placing them to the left of the prevailing indentation level.
13 *
14 * These switches have no effect if '-nlp' is selected.
