Incorrect package homepage when using SSH git URL

[pinpox]

When using a SSH for the package, it is put verbantim into the metadata of the generated package definition.
E.g. using [email protected]:ekzhang/sshx.git for a package generates a working package but it has this metadata section:

 meta = with lib; {
    description = "Fast, collaborative live terminal sharing over the web";
    homepage = "[email protected]:ekzhang/sshx.git";
    license = licenses.mit;
    maintainers = with maintainers; [ pinpox ];
    mainProgram = "sshx";
    };

It would be nice, if this would be automatically filled with https://github.com/ekzhang/sshx instead.
