I concur, although I'm not sure what the option should be called, because
that thing is kinda long. Maybe -maxunencoded?

Yeah, looking at the RFCs again, I believe you're right.

You know ... I'm not sure why that is. You still need to count "> " in
the line length, so it doesn't gain anything. You don't count the CRLF,
but you never count the CRLF for the 78 character limit either.
