[Fluxus] vadd/vsub problems

[gabor papp]

vadd and vsub expect 3d or 4d vectors, but they only work for 3d vectors

(vadd (vector 1 2 3 4) (vector 1 2 3 4))
#(2.0 4.0 6.0)

(vsub (vector 1 2 3 4) (vector 1 2 3 0))
#(0.0 0.0 0.0)

i know that there is a savannah task to improve vadd to expect more than
2 arguments, and it would be also nice if it worked for other vector
sizes than 3 or 4 as well.

best,
gabor
