[logon] preparing for another LOGON snapshot: Barcelona

[Berthold Crysmann]

Dear Stephan and all, 

I have now commited my pending changes to GG, DeEn and HaG. 

Sorry, EnDe still has to wait a while. 

Cheers, 


Berthold

PS: 

I just noted that on loading GG I now receive error messages complaining
about malformed empty diff-lists embedded in C-CONT|RELS and C-CONT|
HCONS. Is it possible to switch these warnings off?
