Yes, it works as you suggest.  The testsuite is unchanged (-stack-list-locals
only prints the type for integers and there are no tests for -stack-list-args).

It might be a good idea to create a test for a reference variable.  Previously
I suggested that a test for your change to val_print could be done in
mi-var-display.exp or mi-var-cmd.exp, but it needn't be as a variable object
and it could presumably be combined with this test in mi-stack.exp.

	* mi/mi-cmd-stack.c (list_args_or_locals): Use common_val_print
	instead of print_variable_value so that type doesn't get printed
	with value.
