FYI, this was originally tested on Internet Explorer which had set the
value to "yes" on whichever version it was at the time (I don't
remember the details atm).  I have no objection to this change though.
IE does not follow the do-not-track specification so I am not
surprised that it differs in other ways as well.

Javascript has an odd concept of true and false:
null, an empty string,  +0, -0, and NaN, and false are the 'false' values.

An object will return true.
