Format changes in source code of Dual-Pivot Quicksort: removing of double spaces

[Vladimir Yaroslavskiy]

Hello,

The Dual-Pivot Quicksort source code contains several
double spaces and it would be nice to remove them, the
changes in DualPivotQuicksort class are pretty trivial:

1. ... is empty  and the call is ...
                ^^
2. ... // (a[k] > pivot1) -  Move a[k] to right part ...
                            ^^
The diff is here:

Note that white space changes are usually ignored by
webrev so the patch file is the place to see the change.

Thank you,
Vladimir
