Thanks for the help.  comment-region is a powerful command useful in
all languages!  I tried to set comment-empty-lines but could not
get blank lines to get commented.

Here is a small .emacs I made to try to comment empty lines when
I do a comment-region command.  It works except for blank lines
in C...

   (setq-default auto-mode-alist
      '(("\\.c\\'"    . c-mode      )
        ("\\.h\\'"    . c-mode      ) ))

   (add-hook 'c-mode-hook 'my-c-mode-hook )

   (defun my-c-mode-hook()
      (turn-on-font-lock)
      (setq comment-empty-lines t) )


What am I doing wrong?
Thanks!

Chris
