-@item same-octave
-This is the default algorithm. Accidentals are typeset if the note
-changes the accidental of that note in that octave. Accidentals lasts
-to the end of the measure and then as many measures as specified in the
-value. This is, @code{1}@tie{}means to the end of next measure,
-@code{-1}@tie{}means to the end of previous measure (that is: no
-duration at all), etc. @code{#t} means forever.
