Summary:                    vtkXMLUnstructuredGridWriter: corrupted output for
polyhedral cells in appended mode
Description: 
The Graphics\Cxx\TestPolyhedron0.cxx test works in ASCII mode, but comment-out
this line and it breaks:

writer->SetDataModeToAscii();

Alternatively, explicitly change it to:

writer->SetDataModeToAppended();

(Binary mode works fine.)

The resulting vtu file has malformed XML. It starts like this:

" offset="588"="1.0"?>
<VTKFile type="UnstructuredGrid" version="0.1" byte_order="LittleEndian"
compressor="vtkZLibDataCompressor">
  <UnstructuredGrid>
...etc."

Still an issue in VTK 5.10.0.

An improved test would try all the different data modes (ascii, binary,
appended) and compressors (zlib, none).
