Will do, sorry. I'm still trying to find a good way to interact with the
bugtracker.

I'm not sure there's a great way to decide what needs documentation and
what doesn't. Glancing through the code in the Emacs tree, these are the
functions that seem to get used fairly often by modes that derive from
tabulated-list-mode:

- tabulated-list-delete-entry
- tabulated-list-get-entry
- tabulated-list-get-id
- tabulated-list-header-overlay-p
- tabulated-list-put-tag
- tabulated-list-set-col

So perhaps start with those?

I got the rest of your comments (thanks!) and will incorporate them into
a follow-up patch once we decide what exactly needs to get documented.
