+ This function is "a step sideways" for uses of deprecated_selected_frame.
+ They should be fixed as above, but meanwhile, we needed a solution for
+ cases where functions are called with a NULL frame meaning either "the
+ program is not running" or "use the selected frame". Lazy building of
+ deprecated_selected_frame confuses the situation, because now
+ deprecated_selected_frame can be NULL even when the inferior is running.
+
+ This function calls get_selected_frame if the inferior should have a
+ frame, or returns NULL otherwise. */
