Some languages reported as unknown even though they're suggested

Observe:

```
temporal@galactica~> curl cht.sh/lisp
Unknown topic.
Do you mean one of these topics may be?

* lisp/ 100
* elisp/ 89
* alias 67
```

Changing the URL to cht.sh/alias correctly gives a list of examples, while lisp and elisp are always reported as unknown. My guess is, something somewhere is storing those tokens with forward slash in the name, whereas the HTTP handling code strips it out from request.
