But the fact that RET does newline and then does like TAB is your own
customization!  So you can't blame Emacs that it is doing what you
told it to do.

That said, I understand that the behavior of RET that you see in
text-mode is not the best behavior.  Clearly it should be changed.

Actually, I've never minded until now.

But I see how it would be strange in text mode.  But in text mode,
indentation is not done very often.  I have told Emacs that RET
invokes newline-and-indent in programming modes (C, Java, Perl, ...)
whereas it does just newline in other modes, like text.

[time passes]

Oh, now I remember that I sent a bug report about newline-and-indent
in text mode, some years back.  Whee.  Yeah.  I guess Emacs just
doesn't like you to use newline-and-indent in text-like modes :-)

FWIW, I get by with just newline quite nicely.  For the kind of text
I write, indentation is not often required.

Hm.  I was going to answer that indent-relative does that, but in
fact indent-relative-maybe also has this strange behavior in the
first line of the file.  I think that might be a bug.

Note that indent-relative goes by tab-stop-list after the end of the
previous line, whereas indent-relative-maybe does not do that.

This line is not blank.
