yes, this is all correct and intended.
we could have petrucci-french instead of the new g1, but we don't have
petrucci-violin (petrucci-alto, etc.) either -- so long we went with
petrucci-c1 etc.
now as I added the g1 variant, for consistency reasons seemed worthwile
to have g2 as alias of g, just like petrucci-f4 is an alias of
petrucci-f since long (I don't know which one was first, f or f4).
I thought about introducing a petrucci-c alias to one of the c-clefs,
but since all five are used frequently (and together -- in different
parts), any choice would be rather confusing than logical.
