These are both expressions of the fact that a `module` directive is neither a
_control-line_ nor a _text-line_. Which is to say that there should be a
preprocessor diagnostic (effective with `-E`) that triggers whenever a `module`
directive is encountered where a _control-line_ or a _text-line_ is required.
In particular, such a diagnostic should only refer to "module directive"s and
not to "module declaration"s.
A diagnostic is required for the following:
```cpp
module;
#if 0
export module m;
#endif
// expected-error@-2 {{}}
export module m2;
```
