Testing session swh-graph:

    - ENOENT shouldn't be logged
    - Use yaml.dump() to display the config (only in debug instead of info)
    - Document how to change the logging level
    - DEBUG level: only return the number of results, to have a readable output
    - pretty-print the meta JSON
    - try to find why ls using zsh plugins that look for .git is slow
	    - maybe lookup() -> O(1) results in the sqlite database?
    - update .status every time it is opened, not only on `ls`
    - nested branch names (e.g., feature/foo) in snapshot instead of %2F
    - origin/archive search
    - swh search CLI, returning origins
