In doing an end-to-end read on -base this morning I came up with a
possible difficulty with simple body canonicalization.
The description says that simple reduces CRLF 0*CRLF at the end of a
message to a single CRLF. But what if the message has no trailing
CRLF at all?
Remember that in the sequence CRLF . CRLF, both CRLFs are part of the
terminator, not part of the message. Thus, a message reading:
in fact has no trailing CRLF on the message. (This could also happen
with BDAT, but that's not widely implemented.)
An approach to this might be to say that simple reduces 0*CRLF to a
single CRLF (which is quite possibly what the current implementations
