That is how grace notes were spaced in the last two stable versions.

Grace notes get 80% the space that a note would get to the prefatory item,
but that 80% space is measured from /left/ edge of the prefatory item, so
for wide items that results in grace notes being placed as close to the
right edge of wide prefatory item as the non-collision condition allows.

Now the space-alist mechanism is more sophisticated, specifying space to
either the left- or right- edge as appropriate for each prefatory item.
I'll try computing the desired grace note position based on this more
sophisticated specification, and propose the change if it looks good.

The proposed fix for issue 724 will add 0.8 staff-space between time-
signature and grace note anyway, by adjusting the non-collision condition.
