Fix #19

This snippet (taken from rbenv) illustrates a way of iterating through an output of lines that supports lines possibly having spaces in them:

```sh
OLDIFS="$IFS"
IFS=$'\n' scripts=(`rbenv-hooks which`)
IFS="$OLDIFS"
for script in "${scripts[@]}"; do
  source "$script"
done
```

Ugly, but efficient. You could maybe take that approach.
