-1 on that patch...

+		my $msghead = $`;
+		my $msgbody = $';

we cannot use $` and $' in SA -- use of them imposes a speed penalty on the
entire perl interpreter.

however, you're right -- we need to fix a bug here.

The test message contains 8-bit data using Content-Transfer-Encoding: 8bit .
This is a valid MIME message (arbitrary 8-bit data is fine according to rfcs
2045 and 3030).  This is damaged by SpamAssassin due to the s/\r?\n/\r\n/
substitution.

I think your patch is on the right track (replacing \r?\n in the headers only,
rather than in both hdrs+body) -- but it needs to be redone without $` and $'.
