Small syntax bug in `lx` man page

[MrAureliusR]

When building from the main branch, and after installing, I run man lxand the "OPTIONS" header ends up not being parsed. Screenshot illustrates this well:

I know next to nothing about man pages and how they're generated, so I don't have a matching pull request. If nobody is available to fix this, I'd be willing to dig into it.

Thanks for this. The manpage here is generated from docbook-xslt scripts, and it's likely the bug is there. But chasing that is going to be a journey, and I wouldn't recommend it.

I expect there's a way we can work around it locally somehow.
