Now that I see that, you're absolutely right and I do apologize for 
bothering you with this.  After looking at that patch (from October 
2018) I do remember when you originally posted it and thinking at the 
time that I needed to pick it up in a future build.  The build from Aug 
21 2018 was 3.0.7 and didn't include your 4924717e fix.  I guess it is 
time for me to move to a stable-3.0.9 build!

Thanks,
Steve
