Isn't the real, operational issue here a question of whether trailing
white space should be hashed? The choices are to say yes, or no, or it
depends on the type byte in the signature.
Have you considered the implications of format=flowed (rfc2646)? Specifically:
4.6. Digital Signatures and Encryption
If a message is digitally signed or encrypted it is important that
cryptographic processing use the on-the-wire Format=Flowed format.
That is, during generation the message SHOULD be prepared for
transmission, including addition of soft line breaks, space-stuffing,
and [Quoted-Printable] encoding (to protect soft line breaks) before
being digitally signed or encrypted; similarly, on receipt the
message SHOULD have the signature verified or be decrypted before
[Quoted-Printable] decoding and removal of stuffed spaces, soft line
breaks and quote marks, and reflowing.
