Of course, we made that change to make keyboard input better on
MS-Windows.  And it _is_ better now than it was before.

I don't think this is the case.  C-M-e does in Emacs exactly what it
should do, it just doesn't do what it does in other applications,
i.e. insert the Euro symbol.  But why should C-M-e do that in Sweden,
when it doesn't do that in other locales?  It sounds like Emacs
behaves consistently here.

I have nothing against mentioning this quirk in PROBLEMS, of course.
Although I don't really agree this is a "problem".

If Ilya can look into this and explain what's going on, it would be
great, of course.
