Or now lore.kernel.org/all/...

That is the link I was originally expecting for when I went back to this thread.

Fair enough, I thought this was more automated than it is. I have some
scripts for writing replies[1] if that helps. I wrote them because I
couldn't find any that would quote emails. (Maybe because it's a pain
dealing with all the encodings). They are geared toward patches in
terms of trimming the email, but shouldn't be too hard to adapt.
