This is a lazy changelog really.

'This is the correct patch' has no technical value.

What is VLA  ? Sure, _now_ its pretty clear since we have floods of 
these patches, but...

In one or two years, people reading it will not understand the logic of 
this patch.

I had to look at the source to understand what was going on, and that is 
not a good sign for a trivial patch like that.
