I am wondering how to coax `show` etc to print a `StaticArrays.SUnitRange` as is, not as a vector of indices. I tried the usual suspects for options in `IOContext`, didn’t work. I am not even sure if this is intended or a bug.

```julia
julia> using StaticArrays: SUnitRange

julia> s1 = SUnitRange{1,2}()
SUnitRange(1,2)

julia> x = (s1,s1)
([1, 2], [1, 2])

julia> show(IOContext(stdout, :compact => false, :limit => false), x)
([1, 2], [1, 2])
julia> x[1] # I want elements printed like this
SUnitRange(1,2)

```

`SUnitRange` is not an abstract range so it will fall back to array printing. It prints like `SUnitRange(1,2)` in the REPL because it has an overloaded `MIME"text/plain"` method. I don’t think there is a way for containers to have their elements to print as `MIME"text/plain`.

Perhaps StaticArrays is missing a standard show method for `SUnitRange`?

Just playing around:

```julia
julia> Base.show(io::IOContext{Base.TTY},s1::SUnitRange{1,2}) = display(s1)

julia> show(x)
(SUnitRange(1,2)
, SUnitRange(1,2)
)

```

You probably want:

```julia-auto
function Base.show(io::IO, s::SUnitRange{Start, L}) where {Start, L}
    show(io, MIME"text/plain"(), s)
end

```

Not me, perhaps Tamas. But exactly I intended that someone builds upon it.
