main: A slightly more compact presentation of the main help text 

This just reduces the amount of space between different elements on in the
main help output from four columns to two. The main motivation here was
to give some of the longer command descriptions a little more horizontal
breathing room, but subjectively I also find the tighter column gutters
easier to scan. Others may disagree, of course.
