Mini with no argument is wrong #args, EINVAL; Find, Grep and Mini say their names capitalised

Mini needs a file but did not say so, so a bare Mini ran and failed EIO. It now requires its argument, refused wrong #args (EINVAL) as every such word is. Its failures, Find's and Grep's start with the builtin's own name (Mini:, Find:, Grep:), as the others' do.
