Strip self-link from top knowls

[kedlaya]

Certain objects in LMFDB have "top knowls" that are included into the text of their home pages (e.g., the Leech lattice). Since knowls are context-free, such a top knowl could appear elsewhere.

In general, it would make sense for a top knowl to include a link to its originating page: it is a natural use pattern to learn about an LMFDB object via a knowl and then follow the link to that object's home page. However, when a top knowl for an object is included in the text of that object's home page, it makes no sense to still have a link to that same page. Would it be possible to modify the code that interpolates the top knowl so as to strip out any link to the current page?

The updated knows code includes many new tools for making sure knowls are
working properly. For example, a list of code and other knowls that reference
a given knowl.

I think it would be bad to have knowl content automatically modified in this way.
Such knowls should have their content updated by a person.

Closing this. If the new tools are somehow inadequate, that can be another issue.
