this renders the same in the manpage and a little more clearly in the
html manual. in the manpage there continues to be no distinction from
regular text, the html manual gets code-type markup (which was probably
the intention for most of these uses anyway).
`fcitx5` and `service.earlyoom` rely on use XDG autostart files to start.
But for X session with only window manager and no desktop manager
(`none` is used), no one can start them.
This options is added to run these autostart files for sessions without
desktop manager to make other services just work.
This windowManager and desktopManager doesn't even have
an option to use it. git history suggests to me that there's no way anyone
finds this useful anymore.
