Actually, the documentation isn't quite right. MIMEDefang
unconditionally wraps the message. Here's the code:
$entity = $parser->parse(\*FILE);
[...]
# Make entity multipart
my ($code);
$code = $entity->make_multipart();
$WasMultiPart = ($code eq 'ALREADY');
There's an escape hatch: You can check the (undocumented, alas) global
variable $WasMultiPart to determine if the original message was multipart.
