  Log Message:
  -----------
  Path validation is not return reachability

The original design for path validation attempted to validate return
reachability by requiring that PATH_RESPONSE followed the same path as
PATH_CHALLENGE.  We removed that long ago, but the text retained echoes
of that choice.

Closes #4064.
