It continued to work until

commit ece789bf5f661cb8f16b50f87a248dedd6e1d8d5

    Issue 5003 unfoldRepeats can be restricted to certain repeat-types
    
    It now takes an additional, optional argument.
    It's a list of symbols representing the repeat-types which should
    be unfolded.
    Possible settings are percent, tremolo and volta.
    The default is an empty list, for which repeated-music is taken,
    unfolding all.
    A new regtest is added to cover the new feature.
    Changes is extended accordingly.
    
    Also correcting two small typos in Documentation/notation/staff.itely

Always a bit of a risk to change the call signature of existing exported
functions.  It may be called by more than just \unfoldRepeats , with
\applyMusic only being a somewhat weird old use case.
