This ticket may have an impact on #13991. It will certainly add more tests to, but I hope changes to this file will improve performance rather than degrade it.

I just noticed that #13991 closed and this was a duplicate with #14228. The changes that I make here will have to be made compatible.

Hey Mike,

I've uploaded a review patch which does some tweaks to the doc. If you're happy with my changes, you can set this to positive review.

I completely forgot these tickets were here. I changed a couple of words because I thought the comment in the documentation that I wrote was unclear.
