Proof step 17 from proof junkref-putbar-01 (previous step)

by ' + bytes0 ≠ [], okbytearray(r0, st), junkref(str, r, putByteArray((by ' + bytes0) .rest, r0, i + 1, st)[r0 -- i ', byteval((by ' + bytes0) .first)]), ∀ r0, st, str, r, i. okbytearray(r0, st) ∧ junkref(str, r, putByteArray(bytes0, r0, i, st)) → junkref(str, r, st) ⊦ junkref(str, r, st)
