is the bracketed quotes just a way of forcing a whitespace character?

[schoinh]

Yes. Is there a better way to do this? (this also gets auto-added by our formatter)

[toloudis]

I'm not aware of a better way and the formatter probably knows what it's doing there because it has to add a line break.
