I wonder if we need to give a warning here about an unknown and
ignored value, by calling something like

	warning("unknown value given to http.version: '%s'", version_string);

here.  We should not trigger noisy warning while reading the
configuration file looking for other variables unrelated to
http.version but this codepath is followed only when we know
we need to find out what value the variable is set to, so it
probably is a good thing to do.  

Thoughts?
