Restyling of XSpectra I/O, 

  by Nadejda Mas and Delphine Cabaret.

The variable ef_r, used to eliminate the occupied states
from the spectrum has been replaced by

xe0              real(DP)                                          DEFAULT=1.d4
                 energy-zero for the spectrum in eV 
                 - must be set to the Fermi level if xonly_plot is .true. 
                   and the version of x_save_file is 1
                   (written with a previous version of the code).
                 - can also be used to set the zero energy for the calculation
                   of the spectrum at an other value than the Fermi energy
                   (for example, for an insulator, in the middle of the gap) 

if the default value is given then the occupied states are eliminated from the
Fermi level.
