I'd address the FIXME right away. Something like this:
```
      if (Style.isVerilog()) {
        const FormatToken *Prev = Current.getPreviousNonComment();
        if (Prev && Prev == State.Line->getFirstNonComment() &&
            Prev->TokenText == "import") {
          return nullptr;
        }
      }
```
