[Users] output not overwritten anymore?

[Christian Reisswig]

Hi Ian, Erik,

thanks for the reply! I played around with IO::truncate_files = yes/no
but without success.
In particular, CarpetIOScalar does not overwrite files (I am looking at the L2 
norm of some grid function) anymore.

cheers,
Christian
