Do the failing cases that do not trigger the new postlen check fail
because the original (mis)counting thinks (incorrectly) that the
rewritten result _should_ fit within the original postlen (hence we
allow an in-place rewrite by passing postlen=0 to the helper), but
in fact after rewriting postimage->len ends up being longer due to
the miscounting?
