[fpc-pascal] URIParser.Unescape

[Thomas Kurz]

Hello,

I have seen that the `URIParser.Unescape` function handles only percent encoding. But it is called within the `ParseURI` function to decode the parameters:

if Decode then
      Result.Params:=Unescape(Result.Params);
      
So I wonder whether it'd have to decode plus signs to spaces, as well? At least I stumbled upon this problem after having received an URL parameter in the style `param+name=param+value`.

Thanks,
Thomas
