bug#4876: Defcustom without keywords

[Juri Linkov]

I noticed a strange defcustom without any keyword in simple.el:

  (defcustom set-mark-default-inactive nil
    "If non-nil, setting the mark does not activate it.
  This causes \\[set-mark-command] and \\[exchange-point-and-mark] to
  behave the same whether or not `transient-mark-mode' is enabled.")

I could guess that :type should be 'boolean, :group 'editing-basics
and :version probably "23.1".  Was it supposed to be so?
