Right, I don't think this is the right function.  That is SPECIFICALLY
for RFC 2047 encoding, which is actually only permitted for some headers
(definitely not References).  Yes, it does folding but that's really just
in the context of creating RFC 2047 "phrases".

That is one option.  Another is that repl(1) could do a better job; I
suppose that is the fault of mhl.
