This is not related to Mew.  It is standard Emacs 23 behavior.

The Emacs 23 NEWS file states:

  ** Changes affecting display-buffer

  *** display-buffer tries to be smarter when splitting windows.
  The new option split-window-preferred-function lets you specify your own
  function to pop up new windows.  Its default value split-window-sensibly
  can split a window either vertically or horizontally, whichever seems
  more suitable in the current configuration.  You can tune the behavior
  of split-window-sensibly by customizing split-height-threshold and the
  new option split-width-threshold.  Both options now take the value nil
  to inhibit splitting in one direction.  Setting split-width-threshold to
  nil inhibits horizontal splitting and gets you the behavior of Emacs 22
  in this respect.  In any case, display-buffer may now split the largest
  window vertically even when it is not as wide as the containing frame.

You can read the NEWS file by typing  C-h C-n.  This will tell you about
other enhancements (or regressions, depending on your point of view).
