Which is easy enough to change.

I suspect I would find it really annoying, by analogy with the overly
aggressive quote-prefixing that is done by `filladapt'.

You're enabling the confusaholics.  If the user doesn't like what RET
does, the the user can bind it to a different function (or, more
likely, invoke a mode that does that for her and perhaps customize the
mode).  Despite the subject, the interesting issue is "what should
`newline' do when invoked from code?"

The traditional docstring says that it moves to the left margin and
handles auto-filling.  Eli's suggestion of `(insert "\n")' doesn't do
that, and it's not what `newline' does when corrupted by
`electric-shock-mode'.  But I think it's useful behavior, and I think
programs should be able to rely on it (as opposed to users who can
modify the behavior of `One-Flew-Over-the-Cuckoos-Nest-mode' by
removing ?\n, or not invoke the mode in the first place).

Of course Stefan is correct that in Emacs, nothing is reliable.  I
don't understand why he thinks it's a virtue, though.
