Configure Git to use Plink

I just had this problem (with a newer version of Git, 1.7.9). I used the answer from VonC, but only a couple of steps were needed:

1. Set the environment variable GIT_SSH to the location of plink.exe
2. Run pageant.exe and load your private key

On 64 bit Windows, the default location for plink is C:\Program Files (x86)\GitExtensions\PuTTY\plink.exe
The spaces in the path no longer seem to be a problem.
