[Nexus] NXgetinfo for NX_CHAR datasets (HDF5 ONLY!!)

Hi all,

i forgot to mention, that the behaviour of NXgetinfo for NX_CHAR datasets 
described above only arises when using HDF5 as the underlying Format.
With HDF4, NXgetinfo returns exactly what we would expect.

Why these differences between the HDF4 and HDF5 NeXus implementation ???

This is in fact a problem, as applications in higher layers cannot rely on 
what they get from Nexus. The results you get depends on the actual HDF data 
format. This way it can hardly be avoided dealing with annoying HDF case 
distinctions in higher layers.

please drop me a line.
