[Pw_forum] wannier interpolation for hybrids

[Nicola Marzari]

Dear Vojta,


this is a very good point, but also probably a question that we should 
discuss
in the wannier forum - I'll forward it there.

Still, I wonder if the simplest solution to this would be to
add an option to pwscf to write out at the end of the scf
calculations also the wavefunctions for all the k-points related
by symmetry - let's discuss this on the wannier forum.
