    Patch that fixes the skipping of the HTML_PARSE_NOIMPLIED flag
    
    For https://bugzilla.gnome.org/show_bug.cgi?id=642916
    
    I just noticed that the HTML_PARSE_NOIMPLIED flag that you can pass to the
    HTML-Parser methods doesn't do anything. Its intended purpose is to stop the
    HTML-parser from forcibly adding a pair of html/body tags if the stream does
    not contain any.
    
    This is highly useful when you don't need this level of strictness.
    Unfortunately, specifying it doesn't work, because the option is not
    copied into the parsing context.
