I wonder. It should be possible to teach the apply function to be quiet by
default, yes? That would be more elegant than dup()ing back and forth.

Yes, it could be possible, but it could mean many changes not only in
the apply functions, but in possibly many other places as well. I
didn't check, but for example if an apply function calls a function
from another part of git and this function uses error(...) in case of
error, I would have to change this function too.

I could also introduce a hack like a global variable that would tell
error() to shut up, but I am not sure that would be more elegant.

Thanks,
Christian.
