once again and for the last time:
- the calculation of electron-phonon coefficients requires some care,
in particular in the choice of the k-point grids. See the README of
example 7.
- the present algorithm is unsatisfactory in several respects and will
be replaced, hopefully soon, by a better algorithm, so nobody is
going to fix it (assuming that it is broken, which I don't believe)
