I suspect this is something that worked many moons ago, but as you've
found out, you can't set 'direction to an empty list, or indeed to
CENTER.
The correct method to make grace notes behave like normal notes would
be to use the same 'direction setting callback which the Stem grob
uses:
#(add-grace-property 'Voice 'Stem ly:stem::calc-direction)

Neil
