This sounds like a good idea.  Is there already an issue for this?  If not, I could create one.

Regardless of whether MAX_STRING_LENGTH is increased, my instinct is that the test should work for long install paths independent of the setting's value.  I wonder if there is a way to adjust the test so that the file name can still be checked in such a scenario (i.e. so that we do not simply add "or '...'" logic to the regular expression).
