This change:
commit 9b463fa8648b7baed95a44f4317cb7402fd8bf1c
Author: Tom Tromey <tom@tromey.com>
Date: Sat Aug 5 18:30:52 2017 -0600
Respect comment-auto-fill-only-comments
Respect comment-auto-fill-only-comments when auto-filling and a
comment syntax is defined.
* lisp/newcomment.el (comment-indent-new-line): Do not check
comment-auto-fill-only-comments.
* lisp/simple.el (internal-auto-fill): New defun.
* src/cmds.c (internal_self_insert): Call Qinternal_auto_fill, not
auto_fill_function.
(syms_of_cmds): Define Qinternal_auto_fill.
broke auto filling in Message mode; the breakage is due specifically to
this change in comment-indent-new-line:

2. Insert at point-max this text (all in one unbroken line):
This is a test. This is a test. This is a test. This is a test. This is a test.
3. Point is now in column 79; type SPC.

4. Delete the last SPC, type `C-a > SPC C-e SPC'.
=> This line is now broken and filled.
Message mode sets "> " and comment-auto-fill-only-comments to nil by
default, but since the above change eliminated checking the latter,
after step 3 the unless condition evaluates to t, so there's no
auto-filling; while after step 4, (comment-beginning) is non-nil, so the
unless condition is nil and auto-filling occurs.

This will probably be no more than a workaround, though.

This change doesn't fix the problem. I don't know what the motivation
for the change that caused this problem was, so I don't know how to fix
it; cc'ing Tom Tromey, who made the change.

I've been discussing this off-list with another person who ran into this
problem, but I haven't managed to reproduce it myself.
I suspect the newcomment.el change is incorrect and should be reverted.
Could you try that? The other changes should, I think, remain in place though.
The basic idea of my patch is to make comment-auto-fill-only-comments
work properly. Without it, setting comment-auto-fill-only-comments and
enabling auto-fill in js-mode will cause auto-filling even when typing a
long line of code, which is clearly incorrect.
thanks,
Tom

Strange; you did try the recipe of my OP? That shows the problem for me
every time (with emacs -Q and well as with my initializations). But see
below...

Yes, restoring the variable comment-auto-fill-only-comments in
comment-indent-new-line restores auto-filling in Message mode.

I haven't looked at js-mode, but it seems strange that setting
comment-auto-fill-only-comments to t there does auto-filling of
non-commented lines...
This prompted me to look closer at Katsumi Yamaoka's patch above, and it
turns out that message-do-auto-fill is not being called, although it is
the value of normal-auto-fill-function in the Message mode buffer I'm
typing in right now; instead, the default value do-auto-fill is called.
When you try my recipe is message-do-auto-fill being used? That may
explain why you can't reproduce the problem. I have no idea why
message-do-auto-fill isn't being called here...

It's not being called because internal-auto-fill calls do-auto-fill
instead of funcalling auto-fill-function. But changing it to do the
latter makes no difference, since message-do-auto-fill also calls
do-auto-fill, unless point is on a message header. (So it's still a
mystery to me why you can't reproduce the problem...)

Well, I'm a bit slow today, but making internal-auto-fill funcall
auto-fill-function together with Yamaoka-san's patch does restore
auto-filling to non-comment lines in Message mode; though I can't judge
whether that's the right fix.

Yes, I think so. I found a way to reproduce the bug (thanks to Yuri
D'Elia) and I am going to push the fix now.
