Moves the iterator to point to the paragraph delimiter characters.
The possible characters are either a newline, a carriage return,
a carriage return/newline in sequence, or the Unicode paragraph
separator character.
If the iterator is already at the paragraph delimiter
characters, moves to the paragraph delimiter characters for the
next line. If @iter is on the last line in the buffer, which does
not end in paragraph delimiters, moves to the end iterator (end of
the last line), and returns %FALSE.
