[R] DEFINES indicator on cprint/p doesn't appear in Visual Studio Code
In version 4.28, we introduced a [R] suffix on variable names in the cprint/p hierarchical display. But for now that [R] suffix is suppressed in the BuildHierarchicalTree() display routine for machine mode, because the presence of the bracket causes VSC to throw the variable away. There is, I believe, a regex expression for valid variable names. That expression could probably be edited to allow the bracketed text through. But for now I am not doing it; it's a bit of a headache to find, and test, and then make sure the double-click on variable value to change that value can still be made to work. I am setting it aside for another time.
