Spell verb *set up* with a space

The verb *set up* is spelled with a space [1].

```
$ git grep -l 'to setup' | xargs sed -i 's/to setup/to set up/g'
$ git grep -l '# Setup' | xargs sed -i 's/# Setup/# Set up/g'
$ git grep -l "test 'setup" | xargs sed -i "s/test 'setup/test 'set up/g"
```

Revert the change for *setup block yields self*.

Change the rest manually.
