Changes fall into one of the following:
- gofmt -s
- receiver name is inconsistent
- omit unused 2nd value from range
- godoc comment formed incorrectly
- err assigned and not used
- if block ends with a return statement followed by else
This closes #98, even if this commit does not do full content text search.
We may revisit that problem in the future, but that deserves its own issue.
Fixes #98
