Crystal ball says that vc-fossil (which is not part of Emacs, AFAICT)
either doesn't instruct Fossil to produce root-relative file names in
the diffs (IOW, "foo" above should actually ne "some/directory/foo"),
or doesn't set the default-directory of the vc-diff buffer to the
directory of the files as named in the diffs.
