Thanks a lot!  Unfortunately I probably won't be able to study this in
detail in the next two or three weeks; I'm currently fighting against a
medical problem, nothing serious, but kind of tiring and I won't
probably find the energy to concentrate on that until the surgery... but
if I do I'll drop a line or two here of course ;)

  Sorry for the delay, and again, thanks for the examples.
