MIME::QuotedPrint::decode_qp destroys user data

MIME::QuotedPrint::decode_qp enforces some “standard” EOL, ”\r\n” namely, on each and every line if no encoded EOL was found (e.g. ’=0D=0A’), thereby changing the checksum of the document if the intended (and found) EOL was ”\n” only (and no encoded EOL '=0D=' was found). It thereby changes the checksum of documents, rendering digital signatures invalid.

What MIME::QuotedPrint::decode_qp should do instead

MIME::QuotedPrint::decode_qp should go with the EOL provided by the user, whether encoded or not.
