That was my thought too. But since git grep gives about 140 of those, it seems
it's a candidate for a separate single purpose cleanup patch for all of them.
On the other hand, it looks like something a compiler could optimize. Also I
wonder if there was a reason for such strange constructs as there are so many
of them.
