Scenario 1. \tocentry is called with section number, then text for section
title, with possible catcode changes.
When you're reading the .toc file, and thus evaluating the \tocentry
command, you can pick up the first argument but simply let the subsequent
argument print itself.
Scenario 2. \tocentry is called with text for section title (again with
possible catcode changes), then the section number.
When reading the .toc file, you need to get at the section number first.
So you pick up the section title after setting catcodes to 11, then pick up
the section number, print the section number, and then you can't just write
the title argument you picked up... because it has the wrong catcodes. You
have to write it back to a temp file, and then input the file.
