[Peter Samuelson] > Hmmmmm. That brings up the minor point of whether N should ever be > anything but (2 * nest_level). Or if you consider nest_level to be zero-based, (2 + 2 * nest_level). It occurs to me, though, that some might prefer the raw presentation look of (2 + 3 * nest_level). I might even prefer it myself. Specifying either of those, or leaving it open as it is now, would be fine with me.
