Yeah, this is clearly an improvement.

Agreed. I didn't try to put these into tables like most of the other
functions are, precisely because the descriptions and examples are too
long to fit nicely. But splitting the running text using <sect4>
seems helpful, and breaking the syntax summaries out-of-line with
<synopsis> is an improvement too.
I did some janitorial work on this (notably, I think some people's
versions of DocBook don't like id strings containing underscores)
and pushed it.
