Ok Hans, with the beta from yesterday the absolute values change size,
but there are some problems still:

1) The absolute value bars are not just "straight lines" when using
\big and friends, but som kind of line that is thicker in the middle.
(zoom i on attached pdf)
2) The horizontal spacing in the \big version seems to be bigger than
for the \bigl/\bigr version (and similar for \Big vs \Bigl/\Bigr). I'd
expect the same spacing (the l and r are just there for the writer to
easily see what is left and what is right).
3) I'd expect that \| gives double bars, like the || one get from
\Vert and not |. This is not so (see the attached file). Moreover, it
is not possible to do \bigl\Vert right now to get a bigger ||.

Mikael
