	* etags.c: (C_entries): Keep track of ()-parenthesis level so that
	functions returning a pointer to a function, a la `signal', can be
	parsed.  This also required new state `fstartlist' to `FUNCST'.
	(SAVE_TOKEN, RESTORE_TOKEN, TOKEN_SAVED_P): 1-deep token save stack.
	(C_entries, CNL): use it to isolate preprocessor directive processing
	from the other state engines.
	(begtk): add '~', for C++ class destructors.
