I was thinking of this, but wanted to go for the smaller patch initially,
but your wish is my command ;-). 

Updated patch below.  Nearly everything here is whitespace changes; the 
second hunk only removes "if (type >= 0 && type <= 2) {" and "}".

ChangeLog:
Adjust a format specifier and remove a redundant range check in
ILGetDisplayNameExW().
