sort container parameters

[Alex Tweedly]

The number of lines being sorted makes o difference.

The number of distinct sorts will - but at a single 'do' for each of 
"several hundreds", you'll not even notice except (maybe) if you are 
benchmarking it (around 5ms per 1000 'do's on an elderly MacBook Pro).
