additional arguments passed to transpose().
Details
These functions take a tabr syntax representation of a chord name and
convert it to quasi-LilyPond syntax;
"quasi" because the result still uses _ for flats and # for sharps,
whereas LilyPond itself uses es and is (mostly).
This is the format used by tabr functions involved in communicating with
LilyPond for music transcription, and they make these final conversions on
the fly.
This can be overridden with exact = TRUE.
