Subject: [PATCH] Also don't match the root directory (#216)

besides the `$HOME` directory.

A `z /` call will cd to the root directory anyway, because of how the
code handles completion:

    # if we hit enter on a completion just go there
    case "$last" in
        # completions will always start with /
        /*) [ -z "$list" -a -d "$last" ] && builtin cd "$last" && return;;
    esac
