Indent size configured value not obeyed by the colon preceding attribute instantiation in a constructor definition

The colon preceding the attribute initialisation in a constructor definition is always aligned 4 spaces to the right, instead of using the indent size configured by the user.

Example:

Foo::Foo(const int pBar)
    : bar(pBar)
{
}

is wrong, while the following would be right if the configured indent size (2 in this case) was used:

Foo::Foo(const int pBar)
  : bar(pBar)
{
}
