Re: Handling of open strings in tablature (issue 5695058)

[dak]

Instead of dontTreatOpenStringsSpecially, something like omitOpenStrings
or skipOpenStrings looks less like an active special action for open
strings, and maybe normalOpenStrings or fingerOpenStrings or
fretOpenStrings suggests that the point is to include them in the normal
calculations instead of treating them exceptionally.

No, I am not happy with all that, but I am pretty sure we will have
users that have a problem understanding that "excludeOpenStrings" means
that we _include_ them in the normal fret distance calculations.
