Fixes #107 - Correct assertion, wrap lines, safety checks

- Smaller test because of assertEquals error condition assertion
- Safety check before error condition assertion to prevent bad-access
- Wrapped lines to 80 columns
- Expect snap-to-lines to be TRUE rather than false, which is the
  default
