In face, the examples _only_ deal with _comments_ in structured
fields. Here, you are correct in that the handling is incorrect
though:
> MIME.decode_words_tokenized_labled_remapped("(=?ISO-8859-1?Q?a?=
b)");
(9) Result: ({ /* 1 element */
({ /* 2 elements */
"comment",
"ab"
})
})

Here, the example says that the command should be decoded as "a b", so
the result is wrong.
