>     url = ssh://-oProxyCommand=some-command
> When cloning a repository with such a .lsfconfig file, Git with the LFS plugin would happily try to invoke ssh in order to get the LFS objects from a host -oProxyCommand=some-command. SSH, however, would interpret that hostname as an -o option and subsequently try to invoke some-command in order to establish a connection (see also man 5 ssh_config).
