Operations with mismatched dimensions

[lbilli]

I was surprised to see that these operations succeed even though dimensions don't match:

julia> using BandedMatrices

julia> m = BandedMatrix(Eye(3), (0,0))
3×3 BandedMatrix{Float64,Array{Float64,2},Base.OneTo{Int64}}:
 1.0   ⋅    ⋅ 
  ⋅   1.0   ⋅ 
  ⋅    ⋅   1.0

julia> m * [1,2]
3-element Array{Float64,1}:
 1.0
 2.0
 0.0

julia> m * [1, 2, 3, 4]
3-element Array{Float64,1}:
 1.0
 2.0
 3.0

julia> m \ [1, 2]
3-element Array{Float64,1}:
 1.0                  
 2.0                  
 6.92307382816255e-310

Needless to say, if a regular Matrix is used instead, DimensionMismatch exceptions are thrown.

Is this the expected behavior?

This is definitely not expected

Fixed in v0.10.0

I'm going to reopen this to remember to add tests.
