Is return the correct thing to do here?

It seems like it used to be that if there were neither package.xml nor manifest.xml it would continue:

```
if package.xml
  process package.xml
else
 process manifest.xml
endif
# continue with code...
```

But it will return if that is the case:

```
if manifest.xml
  process manifest.xml
else if package.xml
  process package.xml
else
  return
endif
# continue with code..
```
