The Harvard Concise says that originally (c. 1675-1725), acciaccatura was
the crush, but it did not have a special notation. The others are all called
appoggiatura. The slashed grace note notation was invented in the 19th
century, and some came to incorrectly call them acciaccatura. Lilypond
propagates this misconception with \acciaccatura.
