ssh: handle IPv6 ssh connections
Performing ssh actions towards Kallithea via an IPv6 connection gave the
following error:

remote:
remote: ValueError: '2' does not appear to be an IPv4 or IPv6 address
abort: no suitable response from remote hg!
This was caused by IPv4-exclusive parsing of the SSH_CONNECTION variable.
With an IPv6 address starting with '2a02:1810:', only the first '2' would
survive.
According to 'man 1 ssh':
SSH_CONNECTION Identifies the client and server ends of the con‐
nection. The variable contains four space-sepa‐
rated values: client IP address, client port num‐
ber, server IP address, and server port number.
So, the client IP address will be the first space-separated word, regardless
of IPv4 or IPv6. Use that knowledge without further parsing.
