This could be considered a reason to improve the indent-line-function in

it could be made to follow the behavior of auto-fill even closer.
Notice, here, how we're no longer talking about electric indentation, but
rather about newline-and-indent. The two topics are distinct.
Yes, but I think we're discussing both in this thread. FWIW, I think
we're in agreement about electric indentation on RET. See my message
here, and also Stefan's reply:

Yes, but how? fundamental-mode is a non-programming mode, so the global
key map needs RET set up for newline, C-j for newline-and-indent. That
leaves lots of mode key maps to be set up. At this point, your
suggestion and mine become the same.
Maybe.
I usually think of html, markdown, and such like, as the "etc." in
"programming modes (etc.)".
Yeah, okay. Which other modes exactly need newline-and-indent on RET
could be a matter of debate, but one possible criteria is "mode has a
meaningful/specialized indentation function".
If you edit the non-code blocks a lot in text mode, `fill-paragraph' is
_exactly_ what's wanted to restore the filling.
If the filling algorithm is perfect, then yes, it could be what's wanted.
I think RET should do the most natural sort of newline, and C-j the
subsidiary one, whatever they may happen to be for a particular mode.
Sounds okay, I guess.
As long as this new mode is divorced from electric-indent-mode, I'd be
happy.
This is a key point.
It could be something called like `old-newline-keys-mode'. Appropriate
major modes would swap RET and C-j bindings, and the above minor mode
would force them all back to (RET C-j) -> (newline newline-and-indent).
This specific behavior is a consequence of using `newline-and-indent'.
No, not at all. It's a consequence of electric behaviour getting
entangled with newline-and-indent.
It's the same if I disable `electric-indent-mode' but bind RET to
`newline-and-indent'.
And if `electric-indent-mode' didn't do `-and-indent' but retained the
electric indent on RET, a similar example is easy to demonstrate:
foo
bar|
Press RET, see the same result.
IOW, text-mode could be considered in trouble if RET triggers call to
indentation at any line.
The two are completely non-competing situations. RMS's happened because
electric indentation was active where it shouldn't be.
AFAICT it's the opposite, but see the scenario above.
To quote the bug report: "and point is at the start of the second line"
Your situation is
a matter of binding (RET C-j) to ('newline 'newline-and-indent) the
appropriate way round. Don't confuse these.
Indeed, for my usage the above binding is sufficient.
