Please don't include shiftround

The shiftround setting breaks many common cases of multi-line indent and outdent for continuation lines.  For example, suppose I have the following code, in a buffer with 8-space indentation:

```
foo(x,
    y)
````

With the default settings, I can > those two lines, and end up with this:

```
        foo(x,
            y);
````

But with shiftround, I instead end up with:

```
        foo(x,
        y); 
```
