Running `netconan -p -i input_file -o output_file`

On this `input_file`:
```
set license keys key "something something"
```
produces a partially anonymized `output_file`:

```
set license keys key "netconanRemoved0 something"
```
when it would ideally produce a fully anonymized file like this:
```
set license keys key "netconanRemoved0"
```
