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