+Temporarily Disabled
+--------------------

+ * "git http-push" is known not to work well with cURL library older
+   than 7.16, and we had reports of repository corruption.  It is
+   disabled on such platforms for now.  Unfortunately, 1.5.3.8 shares
+   the same issue.  In other words, this does not mean you will be
+   fine if you stick to an older git release.  For now, please do not
+   use http-push from older git with cURL older than 7.16 if you
+   value your data. A proper fix will hopefully materialize in
+   later versions.
