There seem to have differing opinions on this topic.
It is certainly easy enough to deal with CRLF or simply LF at the
end of most header lines.
Where the ambiguity hits is on the blank line that separates
the header from the binary text.
I would hope that we wouldn't have a situation where the header
ends with something like the following:
Date: xxxxxCRLF
LF
binary stuff...
or
Date: xxxxxLF
CRLF
binary stuff...
Again, people can live with this, but it is another rock on the
roadway that implementors can trip over.
