I wasn't actually thinking of decoding the headers for things like MIME
content, at least upon read (I assume you're talking about RFC 2047
encoding; personally I doubt you'd notice it on a modern machine, but
I understand where you're coming from). I was thinking of using an
accessor function to take care of that.

Nmh does _not_ know about those things; I'm sort of torn about that.
Right now most tools will combine headers like that into one super-long
header, but the handling is not uniform. Seems like maybe things like
that should be handled by the accessor function; we can give you the
choice of combining headers, or getting first match. Something to think
about!

I'm with David on this; yes, it should be -debug and documented.

Okay, I guess I could see that. The normal case would be to decode the
contents completely

I'm still skeptical that you'd even notice (it isn't 1988 anymore!),
but I think if the API was well designed it should be easy to implement.
