description:
a sequel to getcwd.c revision 1.52 and realpath.3 revision 1.13 by christos:
explicitly mention that NULL is allowed as second argument
in the description part as well.

PR/46618: Onno van der Linden: realpath(3) isn't SUSv4 compliant (and causes
flactag 2.0.4 to dump core). Fix to accept a NULL argument for resolvedpath.
