 The change above looks like a bad synch to me. The FSF 21.3 version
 does not seem to have this change to tq-create.

 I've only started running the current SUMO today. First test
results
 suggest that backing out the change to tq-create should fix the
 problem. 
As far as I can tell, it only changes from old-style backquotes to the
proper backquote syntax.  Since backquotes are used in a *lot* of
places, I'd say that the above change cannot be responsible for the
breakage.
