Extract parameters from string, included quoted regions, in Qt

When parsing any "escaped" or quoted string: splitArgs (from KF5) was immensely useful.

The following source code manages "escaping" and more; from

    one two a\ b "c d e"

it prints

    one
    two
    a b
    c d e

The core of the source code is just a splitArgs call:

#include 
#include 

int main()
{
    QString whole = "one two a\\ b \"c d e\"";
    QTextStream(stdout) << whole << endl << "--------------------" << endl;

    QStringList group = KShell::splitArgs("one two a\\ b \"c d e\"");
    for (auto element: group) {
        QTextStream(stdout) << element << endl;
    }
}
