Review comment:
I am _none_ to happy about using eval, but this is the only way I found
to successfully parse this output bacK
```bash
$ (rap "echo 'exit 123'" EXIT; trap -p EXIT;)
+> trap 'echo '\''exit 123'\''' EXIT
+> trap -p EXIT
trap -- 'echo '\''exit 123'\''' EXIT
++> echo 'exit 123'
exit 123
```
