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,

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.
