it works for SparseMatrixCSC by the way. I don't know what is the "proper" way to fix this. I suspect that just implementing empty!(x::SparseVector) would lead to a suboptimal copy!(dst::SparseVector, src::SparseVector) with possibly redundant reallocations. So I'll leave this to someone more knowledgeable...
