| Attached, you will find a new changeset, that implements the above.

Thank you for writing this patch and David for applying it.

+      error (sprintf("%s: extension has to be a string with finite length",
+                     commandname));

There's no need to use sprintf here since error already understands
format strings.  So you should write

  error ("%s: extension has to be a string with finite length", commandname);
