The status bar had colour tags turned on, so tview read "[connected]"
and "[disconnected]" as tags and dropped them. It dropped all or part
of a nick, a target or a window name holding square brackets the same
way.
The status bar now has colour tags turned off. It wrote none of its
own, so every bracket shows as it is. TestStartUp checks that the
status bar shows [disconnected] at start-up. TestStatusBar checks
[connected], and checks nicks and a /query target that hold brackets.
