This is type safe as it can't be accidentially assigned to something not a
pointer.

This is incomplete because there are more call sites that use
0 instead of nullptr.

For example, you can replace nextItem(0) with nextItem(nullptr)

Anyway, I do not need this patch for now because qconf is
under refactoring, and I will remove a lot of code.

Please come back with a more comprehensive patch
some months later if you are still interested.
