Yes, though I will accept the exception too if it turns out that
the state info people reach complete agreement on a single syntax
and header field name before we finish cache-control.

Any parameter value that may contain tspecials needs to be inside
double-quotes in order to avoid ambiguity.  Since the parameter to
private can contain a list of header names, it needs double quotes.
