Thank you.  I assume that this message replaces the line of 32, which 
tcl did not attempt to print.  Much better than crashing.

I should have specified that not printing is likely for any python older 
than about year.  I have no idea what would happen with current Python 
and tcl/tk older than the 8.6.8 provided with the Windows installer.
