I was surprised to see that ronn replaces the double-hyphen in the tagline with a single hyphen when technically, a double hyphen would be more correct typographically. An actual dash would have been ideal. This commit makes the double hyphen into an m-dash.
Interestingly, most manpages seem to (incorrectly?) use a single hyphen. The manpage of the dash shell uses a proper m-dash (like this commit).
