If we start with the obvious:

  notmuch show --output-headers=date,from,subject,to,cc,reply-to ...

with the default being the current set.

Emitting everything would be easier but seems wasteful.  I just looked
at a random message: in RFC822 syntax the header is 4073 bytes, and the
body is 1116 bytes.  Keeping only the fields that notmuch emits reduces
the header to 295 bytes.  Reply-To is 92 bytes, but not every message
has that.
