remote() revset not working for git repositories

[pyrrho]

After cloning a git repository (hosted on GitHub) either with sl clone git@... or git clone git@..., running sl log -r 'remote()' errors out with,

remote: Invalid command: hg -R my_org/my_repo.git serve --stdio
remote:   You appear to be using ssh to clone a git:// URL.
remote:   Make sure your core.gitProxy config option and the
remote:   GIT_PROXY_COMMAND environment variable are NOT set.
abort: no suitable response from remote sl!

Short of it is, I expect sapling should be running some variation of a git branch --remote invocation rather than an hg -R invocation for git repositories. I'm guessing the suggestion of setting the core.gitProxy config is not relevant to the git-vs-hg concern, but I didn't look too far into that.
