bug#61589: 28.2; Triple-Quote causes emacs 28 to free in Python-mode

[Adam Connor]

emacs -Q recipe: Start with a  file  as follows (not including the
dashed lines):
--------------------

import os



def some_outer():
    """
    Returns an inner function
    """
    print('bah')

    def inner(*args, **kwargs):
        """
        blah blah, 'True' is parsed as the boolean True, '[1,2,3]' as the array
        [1,2,3], etc. -- but in cases where that doesn't work, yadda yadda
        """
        return 55

    return inner
--------------------

Open the file. Above 'some_outer', try  to add

class Foo:
    """

For me, emacs will consistently freeze after I press enter on the triple
quote. The docstrings seem to play a role (if I delete them, it stops
freezing), but I don't know exactly what is going on there.

And by 'freeze', I mean exactly that -- emacs stops responding and
cannot be quit, although I can force-quit it.

Thanks for testing, so I'm closing this bug.

This is  frustrating, as emacs 29 is not available on MacOS except via
compilation. Oh well. On linux, building it is fairly  easy, but looks more
involved  on M1 macs.

In the unlikely case that someone else reports it, the homebrew project
emacs-plus (@29 for that branch) seems  to provide a solution.

Emacs 29 will be released in a few (hopefully a small number of)
months, so you will be able to have it.

No way could I  wait a few months for a working Python environment...
that's the day job, and this was a huge bug for that. I  would have had to
switch to VSCode or something.

But I found a way to build for 29.
