--- Comment #7 from Esme Povirk madewokherd@gmail.com --- OK, I actually can't figure out what this is even for. Anything that would set those isVersion* variables to false is unused. Also, ConfigurationVersion, which is supposed to be kept in sync with CustomizableFileSettingsProvider, doesn't do any processing like that.
So I don't see any way to test this, but I think the sensible behavior is to use the version string as-is by default, and if one of these variables gets set somehow then we can truncate it.
