How can you know the syntax of comments and parameters for all
possible headers? X- headers have arbitrary syntax, thus you can't
sort on X- headers since you cannot perform the decomposition. And
you cannot RFC2047-decode a non-X- but otherwise unknown header, since
you don't know what elements of the header are <text>.
If you don't know the structure of the header the only thing you
can do is collapse FWS and ASCII sort the result.
