[vtkusers] Bug in the vktPlot3DReader when reading multiblock files with FORTRAN byte count

[Berk Geveci]

Hi Ulfar,

I think you are right. It looks like the code which reads
the geometry file has the same bug too. Did you not encounter
that ? I didn't have a multi-block fortran plot3d file when
I was writing that part, do you have an example I can use ?
