What is this '= man' part? Is it for default value? It looks inconsistent anyway.

I don't know we support other format of manual pages. Maybe asciidoc
does the job for us, but do we really care? At least 'info' seems broken..

I wasn't aware of this feature and it seems completely broken. If
it's a leftover from the git codebase, we'd better either to
disable/remove it or fix it.
