This seems fine to me, though as a procedural issue I would suggest that
you not commit anything until the whole series is approved.  (The
alternative seems to be committing unused code, which I think we should
not do in general.)

If this is a hardship for some reason we can discuss it.


I haven't read your patch in depth yet but I wanted to mention a couple
of things.  I'll look at the rest soon.

All of this part looked ok.

I wonder if a global is really necessary.
I didn't check.

AFAICT the vector is only added to with VEC_quick_push.
This will die, though, if there is insufficient space in the vec.

So, something must be missing here -- either an explicit initialization
of the vec, or this should use VEC_safe_push.
