A boundary is caused by delimiter characters, such as
a newline, carriage return, carriage return-newline pair,
or Unicode paragraph separator character.
The index of the run of delimiters is returned in
paragraph_delimiter_index. The index of the start of the
next paragraph (index after all delimiters) is stored n
next_paragraph_start.
If no delimiters are found, both paragraph_delimiter_index
and next_paragraph_start are filled with the length of text
(an index one off the end).
