"""Determine whether this message has excessive quoting.
This modules tests some messages for excessive quoting. It is pretty
simplistic. It looks only at the first text/plain message part if
any, thus it totally misses any HTML only messages if they pass
content filtering.
Also, this doesn't address the problem of a "me too" post with an
"original message" (often an entire digest) included without lines
prefixed by quoting characters.
It should come after MimeDel in the pipeline.
RATIO and QRE should be list settings.
