+Subject: [PATCH] http: limit redirection depth
+
+By default, libcurl will follow circular http redirects
+forever. Let's put a cap on this so that somebody who can
+trigger an automated fetch of an arbitrary repository (e.g.,
+for CI) cannot convince git to loop infinitely.
+
+The value chosen is 20, which is the same default that
+Firefox uses.
