(svn r11731) -Fix [FS#1582]: Clear sprite override data before performing NewGRF wagon attach callback. This stopped 

the callback working for autoreplace and when moving wagons from train to train in a depot.
-Fix (r11724): Don't check wagon attach callback for the chain when moving a single wagon.
