Macros: Add better examples for "prefix" variables

Variables registered with `registerPrefix` are shown in the variable
chooser as `Prefix:<value>`, and that was used to show the "current
value" as the example in the variable chooser.

Add an explicit "example value" to the registerPrefix calls that is used
instead of "<value>" for the expanded example in the variable chooser.
