Ah, yes, perfect.  With this, it works like the original bug reporter
wanted:

              (setq-local fill-nobreak-predicate
              (lambda ()
                (ppss-string-terminator (syntax-ppss))))

But this reminds me that auto-fill-mode in programming modes is a bad
idea in general: Even if it doesn't chop anything inside the string,
it'll still lead to invalid code.

So I think the answer to this bug report is really -- don't use
auto-fill in python-mode, and I'm closing it as a wontfix.
