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).
