I'm worried that we're trying to cram too much into 'list'.  Would
'dominfo' be a better fit for this type of information, without needing
a command line flag?

If we're going to support this in 'list', then we really need to
implement a more generic way to format data into columns, with as many
columns as needed per row.

No space before () in function calls.
