codep argument parsing

I do this:
```
ENTRYPOINT [ \
  "codep", \
    "/usr/sbin/ucarp --interface=eth0", \
    "/usr/local/sbin/haproxy -f /etc/haproxy/haproxy.cfg" ]
 ```

And get this:
```
!! exec: "eth0": executable file not found in $PATH

```

I don't really understand what's happening, I think `codep` parses `argv[1]` wrongly.
