+XXX-Windows Broken behavior to be fixed
+
+Behavior on Windows is broken and should be fixed. However this is a fairly
+corner case situation and no data are being corrupted. This would affect
+central repository being hosted on a Windows machine and accessed using ssh.
+
+This was catch as we setup new CI for Windows. Making the test pass on Windows
+was enough of a pain that fixing the behavior set aside for now. Dear and
+honorable reader, feel free to fix it.
