+Enhancement: Ignore empty lock files
+
+With restic 0.15.0 the checks for stale locks became much stricter than before.
+In particular, empty or unreadable locks were no longer ignored. This caused
+restic to complain about `Load(<lock/1234567812>, 0, 0) returned error,
+retrying after 552.330144ms: load(<lock/1234567812>): invalid data returned`
+and fail in the end.
+
+We have clarified the error message and changed the implementation to ignore
+empty lock files which are sometimes created as the result of a failed upload
+on some backends. Unreadable lock files still have to cleaned up manually. To
+do so, you can run `restic unlock --remove-all` which removes all existing lock
+files. But first make sure that no other restic process is currently running.
