...this is a bit misleading.  

Dividing the pointer size by the element size is _not_ the usual way; 
using the array size is. I am sure this is what you had in mind, just 
the wording is a bit unfortunate.  Perhaps "...which looks like the 
usual way..." and "the size of a pointer" and "the size of elements 
it points to"? And the sizeof expressions do not actually divide 
anything.)

I seem to have a writer's block right now, or I would have proposed
a full alternative, but hope the above gives you an indication?


Definitely okay to commit the other parts of this patch, and let's
just work on this item a bit more.

Thanks,
