Instead of loading the first result in the fuzzy search, how about creating a new issue with the exact title? Then we would be more certain about which issue corresponds to which page. For example, if the page URL (pathname) is `foo/`, but the issue with the title `foo/` doesn't exist, and two issues with titles `hello foo` and `bye foo` exist. In this case, Utterances will map comments to the issue `hello foo`. I feel it would be better if it creates a new issue with the title `foo/` instead.

Basically it boils down to the decision on whether you want to risk loading a wrong issue for comments, or creating a new but unnecessary issue (e.g., `hello foo` might be the right issue for the page `foo/`) when an exact match of the title is not found in existing issues. I feel the former is worse than the latter.
