Actually, the docstring already says that nil toggles.  If you remember
that the docstring is written here to describe the command rather than
the function, then you'll immediately conclude that

  With prefix argument arg, turn on if positive, otherwise off.

only applies when there's a prefix argument, so when there isn't, arg is
necessarily nil and the normal behavior (described on the previous line:

   Toggle recentf mode.

) applies.
