I think in your case the problem is that newlines in the source text do not
indicate paragraphs -- thus you should not keep them. Instead try
interpreting empty lines as paragraph separators:
$ cat tmp.py
import sys
import textwrap
import itertools
import requests
from bs4 import BeautifulSoup
class DocumentWrapper(textwrap.TextWrapper):
def wrap(self, text):
paras = (
"".join(group) for non_empty, group in itertools.groupby(
text.splitlines(True),
key=lambda line: bool(line.strip())
) if non_empty
)
wrap = super().wrap
lines = [line for para in paras for line in wrap(para)]
return lines
page = requests.get("http://classics.mit.edu/Aristotle/rhetoric.mb.txt";).text
d = DocumentWrapper(width=110, initial_indent='', fix_sentence_endings=True)
new_string = d.fill(page)
sys.stdout.write(new_string)
$ python3 tmp.py | head -n10

Rhetoric By Aristotle
Translated by W. Rhys Roberts
----------------------------------------------------------------------
BOOK I
Part 1
Rhetoric is the counterpart of Dialectic. Both alike are concerned with such
things as come, more or less,
within the general ken of all men and belong to no definite science.
Accordingly all men make use, more or
less, of both; for to a certain extent all men attempt to discuss statements
and to maintain them, to defend
