Clang format WebKit style does not match what the clang-format command line tool produces

The code generated by using the clang format plugin within QT Creator does not always match the code generated by the official clang-format command line tool. This is causing a lot of headache for our automated code validation steps on build servers

An example (QSets and literal instantiation):

Qt Creator want a space between the name of the variable and the beginning '{' like so:

QSet<int> myIntSet {
    1,
    2,
    3
};

The clang-format tool using the WebKit style, on the other hand, does not want this space:

QSet<int> myIntSet{
    1,
    2,
    3
};

I prefer the look of the Qt Creator "style" to be honest, but I guess it should be the same as the official clang-format tool, so that automatic tools that do code linting checks won't fail on code generated within Qt Creator?
