Extract function feature does not retain the original code indentation

The original indentation is removed and replaced by the code style that is configured.

Code like

 
connect(
   this,
   SIGNAL(...),
   that,
   SLOT(...)
);

is reformatted to

 
connect(
        this,
        SIGNAL(...),
        that,
        SLOT(...)
        );

which is not desired.

Of course code that is indented a few times needs to be relocated after extraction. But everything below the first line should be kept relative to it.
