33 normal directories have both of them set - you cannot play a directory directly and the UI should descent into it.
34 playlists have "mustDescent", but not "isDirectory" - you don't want the user to browse inside the playlist (unless he really wants)

172 SWIG_VOID(real_returntype_t) hides a return value from swig. This is used for
173 the "superflouus" RESULT return values.
175 Python code has to check the returned pointer against 0. This works,
176 as all functions returning instances in smartpointers AND having a
177 RESULT have to BOTH return non-zero AND set the pointer to zero.
179 Python code thus can't check for the reason, but the reason isn't
180 user-servicable anyway. If you want to return a real reason which
181 goes beyong "it just doesn't work", use extra variables for this,
184 Hide the result only if there is another way to check for failure! */
