Issues with paragraph identification

[jspalink]

It looks like the segmenter. __PARAGRAPH_SEP was recently changed from regex.compile("\r?\n(?:\s*\r?\n)+") to regex.compile("\r?\n(?:\\s*\r?\n)+"). I suspect that's a mistake that snuck in with commit af5d011.

That change looks correct to me.
The change in the regex pattern fixes a deprecation warning when running pytest using the old version:
DeprecationWarning: invalid escape sequence \s

Both the old and the new (changed) version work for me using Python 3.6 and 3.7, but the new version no longer produces the deprecation warning.

Though, if you can give me a reproducible error report, I will happy to reopen and investigate this further.

Ah, my bad. I'm usually using the r prefix on regex strings and was looking at this thinking it's looking for a literal \.
