WINGs: fix incorrect usage of direction variable in updateStartForCurrentTextBlock (Coverity #50192)

Browse Source 
As pointed by Coverity, the variable 'dir' is passed by reference because
the function may update it; as it is never NULL (the function is local)
checking for that does not make sense. From the actual usage, it seems
logical that the check should have been on the value, not on the pointer.
