Currently the uuid-ignore option passed to aedist -rec make it ignore *both*:
1) the change set UUID, to be able to apply it even if
already present in the repository.
2) file's edit-origin-UUID attribute used to copy files
from the right delta.
I think it should be possible to select which behavior is desired, I'm going to add:
* -ignore-change-uuid to achieve 1
* -ignore-file-origin-uuid to achieve 2
-ignore-uuid will imply both options as it is now.
