Re: Point of wrong window used in read-from-minibuffer?

[Richard Stallman]

I did not understand you were talking about two independent patches.
I thought you had written two versions of the same patch--and
installed one of them.

I think I agree now that the patch you installed is a bug fix
and correct.

    My patch tries to make save-window-excursion behave more like select-window
    (and save-selected-window, and with-selected-window).

That is not concrete.  Would you please document in a concrete
fashion the behavior that you believe your patch will achieve?

    Could you give an example where that would happen?

No, but someone would need to check for them in order to determine
whether this change would cause a problem.

    Which problem?

The problem that point moves after
  (save-window-excursion (select-window (next-window)))
That's the problem I saw reported.

I'm saying that changing it to

  (save-excursion (save-window-excursion (select-window (next-window))))

ought to solve the problem too, and the approach is less risky.
