Groff treats "-" as a hyphen by default, not as a minus sign. Since it is used as a minus sign, it's best to escape it.
Noticed by lintian, while packaging ivykis for Debian. Very minor, and quite possibly irrelevant too, as I can't imagine a situation where -1 would need to be hyphenated. But escaping makes lintian happy without an override, and does no harm either.
