If you read the cited text above carefully you will see that the
normalization is still done, but at write time.
Having a \over in memory is certainly better than adding a pair of braces
for each read \over as it was before this patch. If you think that having
a \over in memory should be avoided by all means then please send a patch
that fixes the brace problem your way. I am pretty sure that such a patch
would not be as clean as mine was, because extraBraces() can not be used
if you convert \over to \frac in createMathInset().
