I wonder if they're better with RFC 2047.  That is, suppose we
rendered

Subject: Pretend this is a long field

as

Subject: Pretend this is =?US-ASCII?Q?a=20?=
 =?US-ASCII?Q?long=20field?=

Of course, that would be just unbearably ugly if your MUA doesn't do
MIME headers.

Maybe the best course would be to use two spaces at the beginning of a
folded physical line.
