    relay: Honor DataDirectoryGroupReadable at key init
    
    Our config code is checking correctly at DataDirectoryGroupReadable but then
    when we initialize the keys, we ignored that option ending up at setting back
    the DataDirectory to 0700 instead of 0750. Patch by "redfish".
    
    Fixes #19953

+  o Minor bugfixes (relay)
+    - Honor DataDirectoryGroupReadable when tor is a relay. Previously, the
+      initialization of the keys would reset the DataDirectory to 0700 instead
+      of 0750 if DataDirectoryGroupReadable was set to 1. Fixes #19953. Patch
+      by "redfish".; bugfix on tor-0.0.2pre16.
