[Interest] QSettings keys

[Marian Beermann]

Hi Bertwim,

QSettings isn't really meant as a general-purpose .ini parser. It *can*
sometimes be used for that purpose, but that's not what it's for. This
particular behaviour is perhaps comparable to HTML/XML generators, which
sometimes will escape things that didn't strictly need escaping... the
end result is the same.
