The signature is correct, it just advertises LIMIT as a mandatory
argument.  We could actually make it mandatory, but that would be a
backward-incompatible change, so a lesser evil has been chosen.

advertised-calling-convention is used in only 28 places in all of
Emacs, i.e. it's definitely an extraordinary measure.  So saying that
"C-h f" becomes less useful cannot even be called an exaggeration.
