re-revised last last words

This fixes Roy's nits and another couple that turned up when I read
this out loud to Jim.
================================================================

# Some HTTP/1.0 servers have sent a Content-Type header without a
# charset parameter to mean "recipient should guess".  This is
# inappropriate behavior, and HTTP/1.1 servers MUST NOT omit the
# charset parameter of text media unless the charset of the data is
# ISO-8859-1 (or the US-ASCII subset).
#
# Unfortunately, some older HTTP/1.0 clients did not deal properly
# with an explicit charset parameter.  Senders MAY include a charset
# parameter even when the charset is ISO-8859-1 and SHOULD do so when
# it is known that it will not confuse the recipient.  HTTP/1.1
# recipients MUST respect the charset label provided by the sender;
# those user agents that have a provision to "guess" a charset MUST
# use the charset from the content-type field if they support that
# charset, rather than the recipient's preference, when initially
# displaying a document.
