I suppose it depends on whether you want the first line to be longer
or shorter than the 2nd line. In my mind, it looks better longer. The
{x,} range does make it the minimum, but the non-greedy quantifier
ensures that it breaks as soon as possible after starting the word
that you're in the middle of.

Good point. I don't think I have ever used #sub, so it's never at the
forefront of my mind.
