* lisp/simple.el (eval-expression-print-format): Don't check for

command names and the last command.  Always display additional
formats of the integer result in the echo area, and insert them
to the current buffer only with a zero prefix arg.
Display character when char-displayable-p is non-nil.
(eval-expression): With a zero prefix arg, set `print-length' and
`print-level' to nil, and insert the integer values from
`eval-expression-print-format' at the end.  Doc fix. 

* lisp/emacs-lisp/lisp-mode.el (eval-print-last-sexp): Add arg
`eval-last-sexp-arg-internal'.  Doc fix.
(eval-last-sexp-1): Pass arg `eval-last-sexp-arg-internal' to
`eval-last-sexp-print-value'.  Doc fix.
(eval-last-sexp-print-value): Add arg `eval-last-sexp-arg-internal'.
Set `print-length' and `print-level' to nil when arg is zero.
(eval-last-sexp): Doc fix.
(eval-defun-2): Print the integer values from
`eval-expression-print-format' at the end.

* lisp/emacs-lisp/edebug.el (edebug-eval-defun): Print the integer
values from `eval-expression-print-format' at the end.

* lisp/ielm.el (ielm-eval-input): Print the integer
values from `eval-expression-print-format' at the end.

 ** If the new variable `enable-dir-local-variables' is nil,
 directory local variables are ignored.  May be useful for some modes
 that want to ignore directory-locals while still respecting file-locals.
