Try to use const whenever appropriate to make it clear

	that a string should not be modified.  Nuke some
	trailing spaces, thanks to emacs.  Reduce the scope
	of functions with static.  GNU ident style for
	switch() promote a empty line after the break;


	* comsat/action.c (expand_escape): size and lncount
	could have been use uninitialized.
	(expand_escape): const char *cr.
	(expand_line): cr == "\n\r" make it const.
	variable i and size unneeded.
	variable c initialize to zero.
	(expand_line): obstack_1grow() pass *p instead of c.
	(defaul_action): const char*.
	(run_user_action): fprintf () missing argument.
	(open_rc): const char *filename.
	* comsat/comsat.c (username): const char *username.
	(mailbox_path): const prototype.
	(change_user): const prototype.
	(notify_user): const prototype.
	body and header unneeded variables.
	(find_user): const prototype.
	* comsat/comsat.h: Prototype updates.
