Very true. What made them chose colon?

Oh, that's ugly.

But that's not the only place. There is also the H= field in log lines,
where you want a minimal representation, because log files are 10s of
megabytes long already, and also the input of such things in -bh and
-oMa options. I'd really prefer to have "address-and-port" as one thing
instead of two.

I *thought* I was following an established standard, but obviously I was
deluded. How about 1.2.3.4-25 and 3ffe::1:2:3-25 as an alternative?
