FWIW after reading Bruce's reasoning, I tend towards having no "backups" 
by default (I say "backups", since they are _only_ written when the 
respective branch has changed).

And I do not think that the config variable is a good approach; if you 
want backups or not is a per-case decision.  So your proposal would only 
result in even more confusion.

My preference ATM is to write nothing per default, but only when 
--original <namespace> was given.

Ciao,
Dscho
