Each side of a rename 2to1 could also be deleted by the other side. The code does not expect this. While it luckily works for files, it fails for symlinks as follow:
CONFLICT (rename/rename): Rename a->c in HEAD. Rename b->c in C^0 Renaming a to c~HEAD and b to c~C^0 instead error: cannot read object 0000000000000000000000000000000000000000 'c~C^0'
