The difference is in the mask which is not displayed in the short form. So we actually use a vec_dup for a single-element move, essentially a masked vec_dup where only one element is masked in.
The problem was that the original doesn't use a merging "vec_set" but a "destructive" one where the other elements get ignored. The fix is OK IMHO. Regards Robin
