+Subject: [PATCH] Correct handling of no_proxy .gitconfig options to match git
+ behavior
+
+Explicitly removing the need for a proxy for specific remotes in the
+.gitconfig file via
+~~~
+[http <URL>]
+	proxy =
+~~~
+results in an `error code 12: malformed URL ''` error. Expected
+behavior is to treat remotes for which such .gitconfig entries exist
+the same as if no proxy settings have been found at all.
+
+This issue was found in libgit2 v1.2.0.
+
+This commit fixes the issue.
