https://bugzilla.kernel.org/show_bug.cgi?id=216603 --- Comment #2 from karttu@xxxxxxxxx --- Hi Alex, and Colin, I've never reported any man page bugs before and I basically searched "reporting man page bugs" and ended up at Reporting man-pages bugs (kernel.org) <https://www.kernel.org/doc/man-pages/reporting_bugs.html>. But of course man(1) is an exception :/ Found the issue reporting from GitLab, so it will be there.
