recent message.el quote changes.

The recent changes aren't perfect, I've seen a few versions of the
following in just 2-3 days.  Original text:

`----

When quoted with recent Gnus it looks like:

,----

Maybe the assumption that quoted lines are always preceeded by a blank
line is too much.  My feelings is that it's difficult to get AI to
work, especially intelligent AI. :-)

Wow.  Now you can automatically replace "\n\\(.*\\)\n> >" with "$1\n>> "
or something and repair broken quotes :-)

I think I'm going to write a comb quoting detector and restorer.

BTW, does Outlook always use '>' and never '> '?

Maybe changing the current algorithm to assume that a line is quoted
only if preceeded by blank line into a negative; "a line is not
considered quoted if it starts with > and the next character is
[0-9]"?

I don't think words beginning with ">" are that common that we need to
assume that lines beginning with such words need to be preceeded by
blank lines to be regarded as quoted.  (Five points for anyone who
managed to follow that logic.)  I'm not sure I like the
blank-lines-preceed-quoted-lines assumption, there's no specification
I know of that suggests that.

I'm starting to lean towards my first patch, I'd rather have a simple
algorithm that fails sometimes than a complicated algorithm that fails
sometimes.  As it stands, the simple algorithm fails less frequent
than the complicated as well.

> BTW, does Outlook always use '>' and never '> '?

Maybe that approach is simpler/better, and it is OK with both usefor
and RFC2646.  But it doesn't look good.
