Right, that's what I was thinking.

Yup --- and if you were incautious enough to not exclude the bootstrap
superuser, then you'll also have a very wide Attributes column.  We
can buy back some of that by joining the attributes with newlines.
At some point people are going to have to resort to \x mode for this
display, but we should do what we can to put that off as long as we're
not sacrificing readability.
