As Jeff said, posix.  The body match only matches the content of
messages, no headers.

An internal s-expression.  i.e. the 'code' which is actually executed to
perform the match.

There are no hidden 'features' like this for filters.

But, the xml file can be edited to add additional gui elements for
different filter types - but only for operations supported by the
s-expression parser.

You can currently only set flags, not clear them, so a 'mark as unread'
filter wont work, because 'unread' is actually not the 'seen' flag, you
can't unset that.
