Searching for .: has two 404 pages

[zoffixznet]

Searching for .: on the docs gives two results that end up on 404 pages https://docs.perl6.org/routine/.:: and https://docs.perl6.org/routine/.:%3Cprefix%3E

These are now not indexed, but they are listed on https://docs.perl6.org/routine-operator.html

This is because when link to /routine/sub is redirected to /routine/sub.html.
However, it's broken if the sub is itself starting with ..

They are indexed under different names, for instance, prefix call. But those 404 pages are not nice. Maybe they are related to #1971, since the file name they are generating is not correct.

The first one works now, the second one does not. Searching for both still issue errors.
