I didn't mean to suggest actually changing the header merging rules.
Maybe I should have said "proxies should not merge" rather than "proxies
SHOULD NOT merge". Advice, not requirements.

Basically, we know that multiple implementations get this section wrong
in different ways (the cookie spec, the WWW-Authenticate bugs, the
ignoring-multiple-header bugs Brian mentioned), so this is a really good
place to "be conservative in what you send" (meaning multiples of
Set-Cookie, WWW-Authenticate, and Proxy-Authenticate, and no multiples
of anything else).
