In designing a potential UI for a configuration of `enable_tag_override`,
I found the documentation confusing and lengthy. Here, I've made an
attempt at re-writing this section to be more concise and clear.
I also made a few small changes to the organization of this file to map
explanations to the order of the properties listing at the top. I find
it easier to scan docs when explanations appear in the same order they
are listed at the top. For explanations that span multiple paragraphs, I
provided a subheading, which also helps in linking from other pages.
Finally, I removed a duplicated paragraph from the documentation.
