system is causing this behavior.
I remember trying context while browsing the wiki before so it should work
normally in a brand new environment, but I don't think it's reasonable to
install a brand new distro just to make sure that 'context --help' can work
normally, no matter how problematic the current distro is, as long as it
does not prevent commands from displaying help messages.
