1. work on a project on host_foo in /home/user/src/myproject

2. clone it on host_bar in /home/user/src/myproject

If you set filter_mode = "directory", you can recall project specific commands from host_foo for use on host_bar even though you're working on different machines and the search space won't be cluttered with project specific commands for other projects.
