From 46d21cb7b23f1d3b84ea273f254f838abbd4971f Mon Sep 17 00:00:00 2001
From: Jonathan Nieder <jrnieder@gmail.com>
Date: Fri, 3 Sep 2010 19:56:36 -0500
Subject: Do not unquote + into ' ' in URLs
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().

(cherry picked from commit 730220de8be669257287e9a1f5dde349ace5426a)
This patch from "master" fixes a regression introduced with v1.7.2.
