That method alone is fine with me.

I'd stick to header_str, I think, but I'm not sure.  At any rate: yes.

I'm afraid I don't understand what you mean.

I agree.  I think if we start with the API described above, and leave the
folding for the message to perform, we'll be okay.  We can certainly find out
by writing the code!

I'm sorry, I don't understand.  Could you elaborate?

We have that, right?

"header" is "already encoded", which is another way of saying "do not encode
this."

"header_str" is "text string" which means it will get encoded.

The address or groups thing falls under "object."  I had assumed it would,
itself, know how to become MIME encoded.  This is important, because the
semantics of what gets encoded differ per field type.  So, as_mime_header is
the encoded form.  If you want to offer an unencoded form, as_string seems like
the obvious method.
