         /*
          * check for an auto-matic exit command 
          */
         if( ( pexit = find_door( ch, command, TRUE ) ) != NULL && IS_SET( pexit->exit_info, EX_xAUTO ) )

               else
                  send_to_char( "You cannot do that here.\r\n", ch );
               return;
            }
            if( check_pos( ch, POS_STANDING ) )
               move_char( ch, pexit, 0 );
            return;

Change to:

{
         EXIT_DATA *pexit;

         /*
          * check for an auto-matic exit command 
          */
         if( ( pexit = find_door( ch, command, TRUE ) ) != NULL && IS_SET( pexit->exit_info, EX_xAUTO ) )
         {
            if( IS_SET( pexit->exit_info, EX_CLOSED )
                && ( !IS_AFFECTED( ch, AFF_PASS_DOOR ) || IS_SET( pexit->exit_info, EX_NOPASSDOOR ) ) )
            {
               if( !IS_SET( pexit->exit_info, EX_SECRET ) )
                  act( AT_PLAIN, "The $d is closed.", ch, NULL, pexit->keyword, TO_CHAR );
               else
                  send_to_char( "You cannot do that here.\r\n", ch );
               return;
            }
            move_char( ch, pexit, 0 );
            return;
         }
         send_to_char( "Huh?\r\n", ch );
      }

Auto-Exits were not taking position into account before moving characters, so they could get around while asleep using autoexits if they wanted.
