Comment #1 on issue 2664 by [email protected]: stringTunings snippet in NR 2.4.1

git blame says
3170fd65 Documentation/notation/fretted-strings.itely (David
Kastrup 2011-10-23 15:29:45 +0200 586) \set stringTunings =
\stringTuning <c' g' d'' a''>
and it turns out that many of the \set stringTunings commands have been set
by a convert-ly rule which would need fixing. Replacing them with \set
TabStaff.stringTunings in general would probably not help with FretBoards.
Perhaps one needs an alias "Fretted" or something for both TabStaff and
FretBoards, so that \set Fretted.stringTunings works in either? Or do they
already listen to a common alias? Staff maybe?
