Signing ascii text

I don't think space-collapsed signatures make any sense; they're only going to mess up If you're going to do any canonicalization, do either exactly what PEM does, or canonicalize tabs and trailing spaces out of the message at posting time. Then do the same canonicalization on the receive end before the signature is verified. If a message transfer path is still "lossy", stop using the unencoded body and just live with radix64 encoding. - Bill
