Merge 23bf9f9d95 into 10d3af84b8

The query string send to DDG must not be qouted.

The query string was URL-qouted in #4011, but the URL-qouted query string result
in unexpected *URL decoded* and other garbish results as reported in #4019
and #4020.  To test compare the results of a query like::

    !ddg Häuser und Straßen :de
    !ddg Häuser und Straßen :all
    !ddg 房屋和街道 :all
    !ddg 房屋和街道 :zh
