a330d546 - treat empty `AbstractVector` like empty `Vector` in `print_array` (#57898)

treat empty `AbstractVector` like empty `Vector` in `print_array` (#57898) I don't see why an empty `Vector` should be displayed differently from any other empty `AbstractVector`. Here is an example using views: `Vector` (both master and this PR): ``` julia> [collect(Int8, 1:k) for k in (0,2)] 2-element Vector{Vector{Int8}}: [] [1, 2] julia> Any[collect(Int8, 1:k) for k in (0,2)] 2-element Vector{Any}: Int8[] Int8[1, 2] ``` `AbstractVector` in master: ``` julia> v = Int8[1,2]; [view(v, 1:k) for k in (0,2)] 2-element Vector{SubArray{Int8, 1, Vector{Int8}, Tuple{UnitRange{Int64}}, true}}: 0-element view(::Vector{Int8}, 1:0) with eltype Int8 [1, 2] julia> v = Int8[1,2]; Any[view(v, 1:k) for k in (0,2)] 2-element Vector{Any}: 0-element view(::Vector{Int8}, 1:0) with eltype Int8 Int8[1, 2] ``` `AbstractVector` with this PR: ``` julia> v = Int8[1,2]; [view(v, 1:k) for k in (0,2)] 2-element Vector{SubArray{Int8, 1, Vector{Int8}, Tuple{UnitRange{Int64}}, true}}: [] [1, 2] julia> v = Int8[1,2]; Any[view(v, 1:k) for k in (0,2)] 2-element Vector{Any}: Int8[] Int8[1, 2] ```
