Reformat the pre-defined tests to not be multiple lines.
Reformat the pre-defined tests to not be multiple lines.

This might be overboard as it adds some additional code but the regex off the screen was midly unpleasant.

One additional benefit to this is that you could have a list of excluded tests stored in a separate file and use:

```
ADDL_SELF_TEST_EXCLUDE="$(cat addl_tests.txt)"
```

(note the importance of double quotes to preserve newlines)
