# IPv4 works 
$ ~/.cargo/bin/pijul clone root@127.0.0.1:pijul

$ ~/.cargo/bin/pijul clone root@::1:pijul
Error: Remote not found: "root@::1:pijul"

# this is my real IPv6 address.
$ ~/.cargo/bin/pijul clone root@2a01:4f9:3070:1c9d:::pijul
Error: Remote not found: "root@2a01:4f9:3070:1c9d:::pijul"

The correct syntax I think would have to be root@[::1]:pijul but that doesn’t work either.
