I've some sympathy for this, since the quoting is more often than not unwanted, IMO. But anyhow, I'd stay away from changing the semantics here, at least for QString. It's just breaking the formatting of too much code out there, for little gain.

Actually it results in two spaces

Different behavior for qDebug vs the rest? That does sound hacky too ...
