#554 Unexpected line break in opening-braces in lambda definition

[Taira Ryosuke]

unexpected line break is added to opening-braces in lamda definition.
As previously fixed by https://sourceforge.net/p/astyle/bugs/553/, this is not occur within immediately called lambda.
But, when used break-closing-braces, this occurs again within immediately called lambda.

code:

void func()
{
    // if-else in lambda definition
    auto b = [] {
        if (true) {
            return 1;
        } else {
            return 2;
        }
    };

    // if-else in immediately called lambda
    int c = [] {
        if (true) {
            return 1;
        } else {
            return 2;
        }
    }();
}

I ran astye as follows:

$ astyle --version
Artistic Style Version 3.4.6
$ astyle --options=none --style=1tbs sample.cpp

becomes:
