It is technically ok, and I've committed it.  However, I had to rework
some parts afterwards (see below).  I just didn't want to request yet
another new version of the patch when it is much easier and less
time-consuming for both of us to do it myself.

So take the following as suggestions for future contributions.

I changed that to a more general statement instead of describing just
one very special value here.  Also I added a reference to the node which
discusses the variable.

I've split that into two paragraphs and added a reference to the
prettification node.

I extended the description to be in the order non-nil, multi-level, and
invisible because that's the order from less to more "eye-candy".  Also,
you reference x, y, and z but that example formula isn't there at all.
I've added it.

I changed that back to @ref since @xref{} is only for references at the
beginning of a sentence.
