Exclude tokens in excerpts

Thanks for reporting this issue!

I can see where this would come from, yes – when your entity fields contain tokens, we don’t render those before compiling the excerpt, so the tokens would still be in there. We probably need to provide an option to just remove those “forcefully” from the excerpt, or maybe even render them as far as possible (which is mostly the site:* ones and maybe user:*).
However, since no-one else has complained so far this isn’t high priority right now. In case someone wants to implement this, I’m happy to review, but otherwise I’ll have to wait until more people follow/comment here to express their support.
