maint: Remove unnecessary input validation from @style classes
The Octave interpreter guarantees that the first argument to an old-style
@class is the object itself so there is no need to check for it.
* cd.m, disp.m, argnames.m, char.m, feval.m, formula.m,
vectorize.m: Remove check for 1 argument to function.

Yes, it will be slow, but the use of inline functions is ## strongly discouraged anyway, and most expressions will probably be ## short. It may also be buggy. Well, don't use this function! Use ## function handles instead! function vfcn = vectorize (fcn) vfcn = inline (__vectorize__ (fcn.expr)); endfunction
