bug#62325: Python quotes/apostrophes can cause hang

Hi, all. First bug report for me. I've searched to see if there are 
other reports of my issue, but turned up empty handed.

--- Summary ---
It seems when there are three or more python docstrings (each bordered 
by two lines of triple quotes """) and each containing an apostrophe, 
then the next time a quote docstring is to be inserted Emacs hangs.

I have included a minimum viable example file that reproduces this 
behavior on my machine. Simply replace the angle bracket line 
containing the instructions with triple quotes, and Emacs should hang. 
(In case file attachments don't work I have included the text of the 
file at the end of the email.)

--- Additional information ---
Emacs version: 28.2 (via pacman package manager)
machine: EndeavourOS Linux x86_64 (kernel: 6.2.2-arch1-1)
reply email: gabriel.h.brown@gmail.com

--- start of example file ---
def f_0():
    # inline comment
    < try replacing with triple quotes >
    return 4

def f_1():
    """
    ghbrown's first comment

    return 1

def f_2():

    return 1

def f_3():
    """
    ghbrown's third comment
    """
    return 1

Thanks for your bug report.  I can reproduce that bug with Emacs 27 and 
28, but not with Emacs 29.

Hi Gabriel,

From my testing of your example, the problem appears to be fixed with
the #58780 fix.  Can you test with the latest Emacs in emacs-29 branch
or master branch?  Or you can try the patch attached in #58780.

Apologies for the delay. I finally came into some time to switch Emacs 
versions, and using the makepkg branch for Emacs 29 I no longer see the 
issue I reported.

Thanks again!

Thanks, I'm therefore closing this bug.
