[Pw_forum] plot bands

now I remember...the bands.x code was meant to do exactly the same 
thing. Since the postprocessing code pp.x is doing too many different
things, it was planned to split it into several smaller pieces. The process 
was started but not completed, so that energy bands are still calculated
by pp.x (and bands.x does not work).

thank you for bringing this to our attention: it will be fixed
