            Bug ID: 44479
           Summary: incorrect indentation of arguments of a function call
                    when the function name start on the next IndentWidth.
           Product: clang
           Version: 9.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: -New Bugs

---- INPUT -----
void normalFunctionName()
{
    if (functionName(loooooooooooongParam1, loooooooooooooongParam2,
looooooooooongParam3)) {
        return;
    }
}

---- EXPECTED OUTPUT ----
void normalFunctionName()
{
    if (functionName(
            loooooooooooongParam1,
            loooooooooooooongParam2,
            looooooooooongParam3)) {
        return;
    }
}

---- CLANG-FORMAT OUTPUT---- (extra indentation on the arguments)
void normalFunctionName()
{
    if (functionName(
                loooooooooooongParam1,
                loooooooooooooongParam2,
                looooooooooongParam3)) {
        return;
    }
}


The result have an extra indentation on the arguments of 4 spaces. This happens
always that the name of the function call starts on the next indentation (8
spaces). The indentation should not be measure base on the function name,
should be measured starting with the <<if>> statement.
