 #!CommitTicketReference repository="" revision="21288"
 Clarify the return value of has_filter() and has_action(). It returns a
 boolean if only the first argument is specified. If the second argument is
 specified, it returns false or an integer, which means it may return a
 non-boolean value that evaluates to false (so, 0), so you should take care
 to use the === operator.

 Correct the function definition of remove_filter() and remove_action(),
 which 'accepted' an $accepted_args argument, but did not require or use
 it.

 fixes #19417.
