Locates a paragraph boundary in text. 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 paragraph
(index after all delimiters) is stored in 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).
