bug#17779: 24.4.50; (elisp) `Using Interactive'

[Drew Adams]

I don't even think it should say:

 "Usually this form will call various functions to read
  input from the user, most often through the minibuffer (*note
  Minibuffers::) or directly from the keyboard (*note Reading
  Input::)."

It can say that the form can read input etc. -
that's fine.  But I don't see the point of saying
"usually".  The point is that IF some argument
needs to be obtained by getting user input then
it that CAN be done by the form, e.g. reading from
the minibuffer etc.

But that's a nit.  ("Often" is better than "usually",
if you really want to stress that this is done often.)

No objection from me, at least.  Thanks for
working on this.
