@jomartin-999 Since I'm reviewing for style & format, rather than functionality, I'll defer my review until you've addressed Donal's concerns. (And congratulations on the very cool JIRA ticket number.)

There's one formatting change that I think is important to the readability of the docs. Also this isn't something that you changed, but the note on line 219 does not say anywhere in it that it is for the HSCAN command. Obviously it is a footnote of the HSCAN command so it isn't like that info is missing, but all the other footnotes start with the command they are talking about, and I think consistency is nice.

This footnote applies to HSCAN, ZSCAN and SSCAN, not just HSCAN, so if this change is made, it should mention all three commands.
