Har nu fixat följande i 7.4, 7.6 och 7.8. 7.8 har även fått 2 tester av append_path_nt().
append_path is now a wrapper function for append_path_unix or append_path_nt (more efficient). append_path_unix() and append_path_nt() now uses its combine_path() equivalent. append_path_nt() now handles UNC paths in the relative argument. Added doc for append_path_nt()
