Before sumbitting a message to be included in a multipart/signed message
you should process it into canonical form: that is no isolated CRs and
end of line is CR+LF.
You should process the multipart/signed message in the same way before
verifying the signature.
If you do this then the extra CRs shouldn't matter.
