Yes, it works perfectly for Dired when `split-width-threshold' is nil.
But the problem is that I prefer a wide-screen configuration with
horizontally split windows, so I can't set `split-width-threshold' to nil.

There are a few exceptions where obeying non-nil `split-width-threshold'
is not desirable.  One exception is displaying a list of files in Dired,
and another is displaying the Calendar window.  Maybe there are a few
of others.
