Annotation argument needs to be a constant. Thus, I called stripMargin when
building ExpressionInfo. I am not sure if this is a right way. If so, should we
call stripMargin for df.usage() too?
If we do not care indenting, there exists another solution:
```scala
extended = """> SELECT _FUNC_(array("b", "d", "c", "a"));
4""")
```
Or do you have a better way for adding a newline marker between triple
quotes? Thank you! @marmbrus
