Re: C-x TAB indent-rigidly default set to 4 columns, not to 1

thanks Mike; your solution has still some problem with C-u C-u M-x irFrequent ,
but leads to

  ;; we refer to "Prefix Command Arguments" , 
  ;;  fsf emacs lisp reference manual
    (defun irFrequent (arg beg end) 
      "`indent-rigidly' region with 4 spaces, or prefix-arg spaces if provided"
      (interactive "P\nr")
         (indent-rigidly beg end (prefix-numeric-value (or arg 4))  )    ; 
alternative 1/2
      ;; (indent-rigidly beg end (if arg (prefix-numeric-value arg) 4) ) ; 
alternative 2/2
      )


which looks great and seems to work !
