What extension are we talking about exactly?
Because `man canonicalize_file_name` states the following:

| The call canonicalize_file_name(path) is equivalent to the call:
|          realpath(path, NULL);

Calling realpath with NULL as the 2nd parameter is well defined since
POSIX-2008 [0], if that's what you were talking about.
