[IE] incorrect cursor position after enter in pre blocks

[Karen Ananiev]

Open sample, create preformatted block, type any text and press enter (note that cursor blinks at the start of current line. the new typed text will appear on the new line though). Create a few more lines with text. Click opposite one of the lines to put cursor to the end of it and press enter. In some cases the new line will be created but cursor will appear at the start of the next line.

An unfixed case of #3949.

Observed another quirks of IE selection in <pre>:

1. Load the following content:

   <pre>
   line one
   the second line
   </pre>
   

2. Select word "one" and apply bold style;

• Actual Result: The style been applied with one character shifted off.

The patch (created on 3.6 branch) propose of using <br> consistently in good browsers (preserving text breaks only for IE6&7)inside pre-formatted block which has the following benefits:

1. Reduce selection bug introduced by using text breaks;
2. Easier range position management after line break insertion.

I can't reproduce original TC in IE in latest CKEditor 4.1.2.

TC reported ny garry.yao has been described here: #10554.

I'm closing this issue as fixed.
