Re: customize-apropos

[Luc Teirlinck]

   This message is shown if someone does `C-u M-x customize-apropos' - that's
   what we're discussing, right?

Yes.  Actually, it is shown in four situations:

1. As a result of a bug in some code.  (This is by far the most likely
   situation)

2. If somebody uses C-M-c in the minibuffer (RET or C-j will not work)
   to get around the minibuffer completion functions which are
   designed to prevent such variables from being shown in a Custom
   buffer, unless the user is savvy enough to know how to override
   these completion functions.

3. If the user calls M-x customize-variable or friends from Lisp
   instead of interactively, again in an attempt to override the
   completion functions.

4. If somebody uses an obscure numeric arg, meant for expert users, to
   customize-apropos.

These are all marginal situations.  We are talking about some very
marginal aspect of Custom here, that is only going to be used
_intentionally_ by experts.

Sincerely,

Luc.
