Reverting this part of the change in readconf.c r1.344 "fixes" it for me.
The issue I run into with 'ssh -J host1 host2' is that parse_ssh_uri()
returns 1, in which case there no longer is a fallback to
parse_user_host_port(), so options->jump_host remains unset and the
"Setting implicit ProxyCommand from ProxyJump" path is no longer taken
in main().
