 Thank you for your confirmation, I suspected this might have been the 
case.

 I've got the test suite part done already, so I'll update code and post 
the two changes together.  I think it'll be the best if the code update 
goes in first or both are a single change, so as not to cause regressions 
which might break bisection.
