Alan Donovan a410e98a82 internal/diff: ToUnified may fail ... LineEdits has similar consistency preconditions to ApplyEdits. Previously they were assumed, and bad input would create bad output or crashes; now it uses the same validation logic as ApplyEdits. Since it reports an error, computation of a unified diff can also fail if the edits are inconsistent. The ToUnified([]Edit) function now returns an error. For convenience we also provide a wrapper (Unified) that cannot fail since it calls Strings and ToUnified consistently. LineEdits itself is now private.
