With respect to

 -- Function: safe-length list

the text says

    "If LIST is not ‘nil’ or a cons cell, ‘safe-length’ returns 0."

But running

    (safe-length nil)

gives 0.

Best regards,
Eric Alan Wayman

That case is covered by the first paragraph of the documentation, which 
you didn't quote:

      This function returns the length of LIST, with no risk of either an
      error or an infinite loop.  It generally returns the number of
      distinct cons cells in the list.  However, for circular lists, the
      value is just an upper bound; it is often too large.

No problem.  I'm closing the bug.
