In the buttons,
```auto
@icon:#ExternalCompare:BeyondCompare3,$glob:ExternalCompare+BeyondCompare4
```
"BeyondCompare4" after "+" will be treated as a variable,and then an error occurred:
because BeyondCompare4 is an unkown variable.
So as minus "-" , $glob:ExternalCompare-BeyondCompare4 reports error too.
I have to use underline “\_” instead in DO13: $glob:ExternalCompare\_BeyondCompare4
while in DO12, "ExternalCompare+BeyondCompare4" will be treated as whole variable.
sorry for my poor English!

A fix for that will be in 13.5.1 (after 13.5 goes out).
