This is easy to change, just have to add && target != client to this condition:

https://github.com/ergochat/ergo/blob/681e8b12920bd9aace9ac9484c887760d3e9e649/irc/channel.go#L473

but I'm not sure I actually want to do it, since the anomalous nature of the nick list is an effective hint to the user that they're in an auditorium.

counter point: it can't be a hint to the user that they're in something if they're not actually shown to be in it

They know that they're in it because they get the JOIN line, which generally results in the client opening a window / buffer / "query" for the channel :-)
