* windres.h (ESCAPE_*): Define standard escape sequences.

	* rclex.l (handle_quotes): Handle standard escape sequences.  Warn
	about an unrecognized escape character.
	* windres.c (unicode_print): Print standard escape sequences.
	* rcparse.y (acc_event): Initialize $$.next.
	* resbin.c (bin_to_res_menuitems): Don't set MENUITEM_POPUP or
	MENUITEM_ENDMENU in the menu item flags.
	(bin_to_res_accelerators): Allocate a structure (the old code
	never worked).
	(res_to_bin_accelerator): Correct the test for setting ACC_LAST.
	(res_to_bin_dialog): Save the extended style rather than saving
	the style twice.  Remove useless shadowing length variable.  Set
	the length of control data correctly.
	* resrc.c (write_rc_dialog): Don't print the class or menu if the
	string length is zero.
