Nothing is never completely obvious. We always put a change log explaining
why a change is made. 

Also, it may seem obvious to you because you are using this function.
I have never used this function, and I am not interested in learning how to
use this function to make this simple change, which is why I asked for more
details.

Ah, I didn't find it because it was renamed in the mean time.
