Let's either fix the guards or Qt Creator [
https://bugreports.qt.io/browse/QTCREATORBUG-7317 ]...

Other KDE projects would have the same issue, it's apparently not very
bit if only 263 files use it:

I would delay this change until the tool support it, and especially
for frameworks I would not use it.
So ending up with some files using it and some not does not look clean
for me, it's a distraction (also in git history).

Applying full astyle is IMHO not OK, and even against efforts of
everyone who keeps eye on proper coding style while doing code

Secondly, breaking git blame is unacceptable. Unlike file renames,
there's no equivalent of --follow or ignoring whitespace while
patching, it's a massive irreversible break in history.

People who try this would have to work with scripts like these [
http://stackoverflow.com/questions/5098256/git-blame-prior-commits ]

If someone cares enough, it's possible to edit history to fix some
issues deep in entire history, disable git hooks, and push changes.

I am OK with slots, includes and cmake changes, these bits are local enough.
