The message window has colour tags on, so tview read square-bracket
text in nicks, channel names, reasons, topics and message text as
tags. It dropped that text or changed the colour of the rest of the
line.
A new escape in internal/cli/ui.go writes each "[" as "[[:]", and
app.go applies it to every part of a line that comes from the user or
the server. tview.Escape is not used: it misses bracket pairs holding
symbols such as "|", and tags with a URL.
Lines for other server commands now show the command, such as
"[MODE]", which tview had read as a tag.
