D19621: ViewPrivate: Make deselection by arrow keys more handy

[Dominik Haumann]

  The unit test is good, but it does not yet test the right-to-left case (e.g. arabic text). Could you add one for this as well?
  
  Maybe you can even use KateViewTest::testDeselectByArrowKeys_data() along with QFETCH to reuse the same code in the test function (see other usage of QFETCH).

Since we have this line twice, I suggest to move this after line 2791 as follows:

  const bool moveToEndOfSelection = selection() && !config()->persistentSelection();

Then, you can use a simple `if (moveToEndOfSelection) {...}` which is a bit more readable.
