Removed extra astuce +ei-s after discussion with Eric.

Comment from Alessio (13/12/2014):

Additional details:

That +ei showed up in r259 (16/08/2012) of the coupling repository, when David Sinuela merged the version of SixTrack for the coupling (frozen at official SixTrack 4.2.13dev, 18.10.2010, between r84 and r100, as far as I could reconstruct) with the official one (4.4.42dev, 15.07.2012, r132-133). The spotted "+ei" belongs to these lines:

+if fio
      read(ch1,*,round='nearest')                                       &
     & idat,(ilm0(m),m=1,40)
+ei
+if .not.fio
      read(ch1,*) idat,(ilm0(m),m=1,40)
+ei

Those "fio" related lines appeared in r122 and disappeared in r146 of official SixTrack, so they were added by David (r259) and deleted (not all...) by me (r443).
