Need to deploy from a git subdirectory (patch included)

[ex-nerd]

I have a need to deploy only a subtree from a git checkout. There is some churn in the upstream capistrano project about doing this, but it's enough for my needs to just adjust the path that rsync_with_remote_cache pulls from. I'm attaching my patch below, in case you're interested.
