Sorry for the misunderstanding.  Even in win 3.0, a plain
simple <enter> will insert a new-line into the MLE.  The
problem is that the dialog manager will never let it happen.
As for <ctrl>-<enter>, it is not an implementation
restriction but rather what Microsoft's own windows apps do
(for example Edit Summary Info in W4W).

You can use just plain old <enter> if you want, if you are
willing to go through the hoops I described.  Also, I don't
think the behaviour *has* changed.  I seem to recall that
hitting <enter> in a win 2.x dialog would always activate
the Default PushButton, regardless of the keyboard focus.
