This hooks into some of the functionality for structured matrices in LinearAlgebra, and assuages some of the concerns raised in #265. After this, sparsity is often preserved when broadcasting over a RectDiagonal:

julia> E = Eye(2,4)
2×4 Eye{Float64}

julia> 2E
2×4 FillArrays.RectDiagonal{Float64, Vector{Float64}, Tuple{Base.OneTo{Int64}, Base.OneTo{Int64}}}:
 2.0            
     2.0        

julia> E .+ 1
2×4 Matrix{Float64}:
 2.0  1.0  1.0  1.0
 1.0  2.0  1.0  1.0

Perhaps this warrants v1.1 as its a "new feature"?

Yes, this may go in the upcoming 1.4 release. The version is already bumped on master, but it hasn't been tagged yet
