did_action() returns true the moment a hook is initially run, leaving you no way to tell if the hook is still in progress. Hooks can be nested and this checks the entire stack, versus current_filter() which only identifies the final hook in the stack. This commit also introduces current_action() for parity.
To tell if a hook has completed, one can use did_action() and ! doing_action() together.
The functions do not require an argument. In that situation, they indicate whether the stack is empty.
