As the BEAM checker correctly points out, the conditions on lines 430 and 485
are always false. I'm keeping them as assertions for documentation purposes.
The proof is left as exercise to the reader.
Hint: use conditions on lines 307 and 311 and the fact that old_len and
old_arg are both unsigned entities.
