4 * Tests for the options '-sob' and '-nsob'.
5 *
6 * The option '-sob' swallows optional blank lines.
7 *
8 * XXX: The manual page says: "You can use this to get rid of blank lines
9 * after declarations."; double check this.
10 *
11 * The option '-nsob' keeps optional blank lines as is.

15 * FIXME: There are lots of 'optional blank lines' here that should be
16 *  swallowed.
