The draft standard includes the idea that grace notes should have
modifiable lengths just like regular notes, and suggests that the
software package should set the default length, although it might be
more prudent to add this info to an extended L: field or create a new
field so that all the info is in the tune. This length should
definitely *not* be derived from the standard L: field itself. One
shouldn't have to change the way grace notes are indicated based on
changes in L:, and I defintely don't want to have to write a Highland
pipe jig (typical grace = 1/32) like:
L:1/8
K:HP
{g//}A{d//}A{e//}A {g//e//f//}e2 f | {g//}ec{G//}c {g//e//f//}e2
instead of the much more legible
L:1/8
K:HP
{g}A{d}A{e}A {gef}e2 f | {g}ec{G}c {gef}e2
