 * Tests for the options '-v' and '-nv'.

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