+Repo that contains the latest/current version of a file is not accessible.
+Can git annex whereis find the last available version of a file in other
+repos (or a specific repo)?
+
+I can looping through commit log and running whereis for each commit until
+an earlier version of a file is found, but perhaps there is a better way to
+do it with a single command?
