Only 'verified' stanzas with 0 or >1 path components should end with "/"

Handle good things like:

```ruby
url "https://example.org/download",
    verified: "example.org/download" # This is fine.
```

And bad things like:

```ruby
url "https://example.org/",
    verified: "example.org" # This should end with a slash.
```
