4 * Tests for the options '-v' and '-nv'.
5 *
6 * The option '-v' enables verbose mode. It outputs some information about
7 * what's going on under the hood, especially when lines are broken. It also
8 * outputs a few statistics about line counts and comments at the end.
9 *
10 * The option '-nv' disables verbose mode. Only errors and warnings are output
11 * in this mode, but no progress messages.
