As you say, you can solve this problem with

 graph twoway (mspline  weight length if  foreign==0, lp(solid))
(mspline  weight length if  foreign==1, lp(dash)), scheme(s2mono)

but it is not clear why you don't like that solution. I don't know
another solution. I wouldn't call this a bug, but you are at liberty
to describe it as a bug from a user's point of view.
