docstring: Appends a path to a given property path.
  
  If the base path is empty, the appended path will be returned unchanged.
  If the base path is not empty, and the appended path starts with a
  squared opening bracket ("["), the concatenation of the two paths is
  returned. Otherwise, the concatenation of the two paths is returned,
  separated by a dot (".").
