It seems this command should do the same thing as currently `dcl-save-option'
and `dcl-save-all-options' from emacs/lisp/progmodes/dcl-mode.el do,
but more generally.
These commands make a Local Variables section with prefix/suffix strings
extracted from `comment-start' and `comment-end'. But the result is not
always nice. For example, in Emacs-Lisp mode the value of `comment-start'
is ";", but a nicer prefix would be ";;" or ";;;". Perhaps some modes
should override this value with a new variable like `local-variables-prefix'.
Also the local variables list for `dcl-save-all-options' is not general.
A better choice is a list like used by desktop.el to save the values of
local variables in the desktop file, i.e. the option `desktop-locals-to-save'.
