[exim] Message size checks on spam ACLs

There's been some discussion of late on the SpamAssassin mailing list
about spamd memory usage skyrocketing for Exim users. The current
thinking is that the persons reporting this problem are not checking
(and thus limiting) the size of messages being sent to spamd. I noticed
that the spam ACL examples in the 4.5 spec don't include (or even
mention) size checks. Is it possible to get this added to avoid
confusion?
