This patch has caused Coverity to complain, correctly AFAICS, about
dead code in cube_coord_llur in the back branches:

1628         /* Inverse value if needed */
1629         if (inverse)
>>>     CID 1463943:  Control flow issues  (DEADCODE)
>>>     Execution cannot reach this statement: "result = -result;".
1630             result = -result;
1631     
1632         PG_RETURN_FLOAT8(result);

Seems to be due to sloppy division of changes between f50c80dbb (which
was not back-patched) and 563a053bd.  Please fix.
