I created a `detach` script, being a wrapper around `nohup`:
```
#!/bin/bash

/usr/bin/nohup "$@" &> /dev/null &
```
and I want to get bash-completion to work for this script.

I try to use `complete -c detach`, but for all arguments there is an addition from the utilities from `PATH`.

How to properly implement bash-completion for my `detach` utility?
