I'm not quite sure what you mean, but I implemented ; in lib/args to do optional
argument values, and just fixed a cp.c bug where I wasn't handling the "not set"
case properly?

It's also used in --color for ls, a couple places in nsenter and unshare,
skeleton.c demonstrates it...

I _think_ it handles short arguments properly, but could easily have missed a
case...
