Merge branch 'tb/connect-ipv6-parse-fix' into maint
We did not parse username followed by literal IPv6 address in SSH transport URLs, e.g. ssh://user@[2001:db8::1]:22/repo.git correctly. * tb/connect-ipv6-parse-fix: t5500: show user name and host in diag-url t5601: add more test cases for IPV6 connect.c: allow ssh://user@[2001:db8::1]/repo.git
