How to see command line arguments passed to program in core.sshcommand?

Hi Everyone,

I'm working in an unusual setup on WIndows. I need to 'git clone' over SSH, but a third party program has to handle the tunnel. It happens by using this git configuration:

    git config --global core.sshcommand "tunnel.exe ... <path-to-public-key>"

After I execute the 'git config' command, I open ~/.gitconfig and ensure the path is correct and quoted per Windows standards.

So far the result has been a failed authentication, which seems to indicate something went sideways using the public key. I don't receive an error from Git or or the tunnel program relating to a "file not found" (or any errors for that matter until authentication fails).

I need to spy the command line arguments being passed around, but I have not been able to do so. 'git clone -verbose' is ineffective, and -vvv is rejected as an unknown option.

How do I see command line arguments passed to the program in core.sshcommand?

Thanks in advance.
