[syslinux] [PATCH] Fix hyphen escaping in manpage

[Philipp Hahn]

Debian converts hyphens to minus-signs by default
<https://lintian.debian.org/tags/hyphen-used-as-minus-sign.html>. If
this is manually disabled for testing, some dashes are still wrong.

Convert those remaining hyphens to minus-signs by escaping them.
