Since 9d2e942 (decode file:// and ssh:// URLs, 2010-05-23) the URL
logic unquotes escaped URLs. For the %2B type of escape, this is
conformant with RFC 2396. However, it also unquotes + into a space
character, which is only appropriate for the query strings in HTTP.
This notably broke fetching from the gtk+ repository.
We cannot just remove the corresponding code since the same
url_decode_internal() is also used by the HTTP backend to decode query
parameters. Introduce a new argument that controls whether the +
decoding happens, and use it only in the (client-side) url_decode().
