Hmm, I can't find the one I was thinking of. GetLongFileName correctly
sets the case of all but the final part, and FindFile can be used to
find the last part, but that's not what I recall.

GetFinalPathNameByHandle works, and is documented to do so, but (a) it
works on an open file handle, so you need to open the file, and (b)
it's Vista and later only...
