All definitions should be indexed

[burblebee]

It was decided at the Rap. mtg that all definitions should be indexed, i.e., definitions which use \term{} should be fixed to use \defn{} or \defnx{}.

The fun part of this is that some definitions use \term and have an \indextext next to it. I agree \defnx is technically superior, though. For what it's worth, there are 684 mentions of \term, which should probably all become either \defn or \placeholder or something else.

I think PR #980 addresses part of that. It's pending review.

I would have been nice to mention #329 in PR #980 to avoid duplicate work...

That's true. I find it useful to browser the pending pull requests periodically to see what's pending. Feel free to edit pending PRs with issue links as you find them.
