[using 0.65.1 it returns its argument if there is just one]

It will in 0.90.0: this has already been altered:



    o   expand.grid returns a data frame even for one arg

I am not sure that is what I think it should do (no expanding goes on)
but it is what the documentation says and the prototype does.
