That needs to be requested from Google. As you can see Google is showing a result on Wikidata titled "M-C M-L", but the page itself is not named that way, but "M-C L".

Making an analogy, this is not that a book has the author name misspelled, but that it is misspelled in the library catalog, and when you go pick the book from the shelf, it is actually correct on it. In this case complaining to the editor would not be too helpful. It's the library that needs to fix its catalog. In this case Google.

It is expected that Google will notice and fix the copy automatically... but we don't know when it will do that.

I see a new function in Google "Send comments to Google" that lets you provide feedback for a result item. Maybe you could contact Google that way to ask them to fix that entry?

Regards

PS: I would recommend not to continue stating the full name that should-not-be-named. Given that there should be zero results for that one, and this is a public mailing list, I see a risk of searches for that name leading to this very thread.
