IE9: linking a word doesn't work right when line ends with BR.

[Jakub Ś]

1. Paste in the below code in Source mode

   <p>
   	test a test testing<br />
   	test a test2, testing a test<br />
   	another test line<br />
   	one more test line</p>
   

2. Switch to source and use tab to get focus in content area.
3. Using arrows go to second line
4. Select word test2
5. Click on Link button, enter URL and click OK button

Results: Notice that instead of test2 you get est2, linked. Selection was moved one letter to the right. The same thing will happen if you select whole line.

Reproducible only in IE9 from CKEditor 3.5.1
