        * which-func.el (which-func-maxout): Increase default to 500000.
        (which-function-mode): This is now the "real" name of the function.
        (which-func-mode): Now an alias.
        (which-func-mode-global): Name deleted.

So the function was called which-func-mode, then renamed to
which-function-mode, and the old name kept for compatibility.

It took me all of a grep in lisp\ChangeLog* to find it ;-)
