This fixes the issue with add -p . mentioned somewhere else on the mailing list.

Did you find a reason why we passed magic literally, i.e. short magic
was passed as short magic and long magic as long magic before?

I cannot think of any reason why that would have been the case,
but I assume there had to be a reason for that.


Another note: This collides with the attr system refactoring, which I
postpone redoing until the submodule checkout is done, so maybe
you want to pickup this patch:

which only relies on one patch prior
