bug#17446: 24.4.50; What is the situation around `called-interactively-p'?

[Stefan Monnier]

No, `newcmd' is an expression, so (cdr newcommand) contains arguments
that need to be evaluated.  In some/many cases this evaluation is
trivial (the args are self-quoting, like nil or integers), but sometimes
the args can be things like (region-beginning).

These are the only interesting cases.  The other cases (subrp and
symbolp, AFAICT) are trivial.
