vertical movement without anchors

[Werner LEMBERG]

The NR, section `Text alignment', says

  Vertical alignment is a bit more complex.  As stated above, markup
  objects can be moved as a whole; however, it is also possible to
  move specific elements inside a markup block.  In this case, the
  element to be moved needs to be preceded with an anchor point, that
  can be another markup element or an invisible object.  The following
  example demonstrates these two possibilities; the last markup in
  this example has no anchor point, and therefore is not moved.

    \relative {
      d'2^\markup {
        Acte I
        \raise #2 { Scène 1 }
      }
      a'
      g_\markup {
        \null
        \lower #4 \bold { Très modéré }
      }
      a
      d,^\markup {
        \raise #4 \italic { Une forêt. }
      }
      a'4 a g2 a
    }

However, this seems no longer be true (and it wasn't correct for 1.18
either): The last text `Une forêt' is moved up even without an anchor.

When has this changed?  Or maybe there are still situations where an
anchor is needed, thus the example has to be improved?
