Currently file externals *must* always be from the same repository, because
they are just switched files with a bit of special UI on top of them. (See the
original introduction text of file externals)
We didn't fix this limitation for WC-NG yet, even though we should be able to
describe a new working copy for just a file. (An issue would be that we can't
use the normal update editor to describe changes on just a file, but that is
easy to work around)
I think you can assume that for a file-external no unswitched BASE_NODE exists,
while for a normal switched path there most likely is a BASE node.
