`php -a` treats lines starting with `#` as comments when deciding if
the provided statement is valid.
So it passed `#[MyAttr]` to the parser after the user hits enter,
causing a syntax error for multi-line statements..
With this patch, the following snippet is parsed correctly
```
php > #[Attr]
php > function x() { }
php > var_export((new ReflectionFunction('x'))->getAttributes()[0]->getName());
'Attr'
```
