Given the existing stipulation that path_contains_parent_reference() must only be invoked on canonicalized paths, we can simplify things in the wake of commit c10f830c5. It is now only possible to see ".." at the start of a relative path. That means we can simplify path_contains_parent_reference() itself quite a bit, and it makes the two existing outside call sites dead code, since they'd already checked that the path is absolute. We could now fold path_contains_parent_reference() into its only remaining caller path_is_relative_and_below_cwd(). But it seems better to leave it as a separately callable function, in case any extensions are using it. Also document the pre-existing requirement for path_is_relative_and_below_cwd's input to be likewise canonicalized.
