problem with require-final-newline

problem with require-final-newline

[Charles Jamieson]

   I have the line

	(setq-default require-final-newline t)

in my .emacs file.  When I save a .txt file without a final newline, I 
am asked whether to add a newline.  When I enter C-h v 
require-final-newline, I am informed this variable is set to query.

    However, when I save a .cpp or.h file without a terminating new 
line, the newline is silently added.  In fact when I enter C-h v 
require-final-newline, I am informed its value is set to t.

     Why is this variable not being set consistently across file types?

My guess is that something like this is lurking somewhere (either in
~/.emacs, default.el, or site-start.el):

(add-hook 'text-mode-hook
	  (lambda ()
	    (set (make-local-variable 'require-final-newline) 'query)))

CC Mode does this to help you.  A C++ (etc) source file absolutely
requires a final newline to be syntactically correct, I think.  If for
any reason you don't want this, you can set the (buffer local) value to
nil or 'query in a hook function.

Different file types have different requirements, or lack thereof.
