Hi all,

While the previous attempt[1] was missing some important aspects, it's
a valid problem to solve, so I figured I'd take a look myself. This
ended up turning into a slightly wider cleanup, but I think the end
result is nice enough.

As usual I don't have anything to test this on, so if there are any
silly mistakes left that the compiler couldn't catch please do let me
know.

Thanks,
Robin.
