Spaces are lost when pasting content copied on other website

[Wiktor Walc]

1. Copy changelog for CKEditor 4.5.0 Beta from ​https://github.com/ckeditor/ckeditor-dev/blob/major/CHANGES.md

2. Paste it into the editing area (I used the standard preset), use e.g. the editor here: ​http://ckeditor.com/apps/ckeditor/4.4.7/samples/replacebycode.html

3. Result: spaces are lost e.g. in the sentence that starts with "All drag and drop operations" the space is missing before "editor#paste".

We cannot fix this. Chrome loses these spaces - they are already lost when getting data from data transfer.

The funny thing is that if you change the changelog's text so editor#paste does not start the line, everything works fine :D.
