Leads to a 404 page: https://latest.datasette.io/fixtures/-/explain?sql=with+x%28c1%2C+c2%2C+c3%29+as+%28%0D%0A++values%0D%0A++++%28%27a%27%2C+%27b%27%2C+3%29%2C%0D%0A++++%28%27b%27%2C+%27c%27%2C+4%29%0D%0A%29%0D%0Aselect+%2A+from+x

That's because I only built a test plugin to demonstrate the new feature. But... it would be better if it worked anyway - it makes for a better live demo.
