Enter prepends newline sometimes

[Tobiasz Cudnik]

Enter prepends newline sometimes, instead of splitting actual line.

1. Using following source:

   <strong>a</strong>b^
   

2. Move cursor to the left, between "a" and "b"
3. Hit enter, empty newline will be prepended

Issue doesn't exist when moving from left to right.

Reproduced in r3461. Works fine in public demo.

Confirmed. I have the following result after ENTER:

<p>
	<br />
</p>
<p>
	<strong>^a</strong>b</p>

I've identified the bug was caused by CKEDITOR.dom.range.checkStartOfBlock, which is under construction in #3367, I'll attaching the TC for this ticket at there.
Leaving this one opened and re-eval after #3367 is fixed.

Unit Test Case

[Frederico Caldeira Knabben]

The proposed change is wrong because it changes an intrinsic feature in the checkStartOfBlock feature, as it's related to the "visual" representation of the range, not to the precise position of its boundaries. For example:

<p><b></b>^Example</p>

The above range must return "true" for checkStartOfBlock.

Replying to fredck: My fault, definitely the previous was a wrong fix.

[Garry Yao]

But I still want to confirm if it's good to substitute '!inlineChildReqElements ' with 'CKEDITOR.dtd.$empty' also.

[Frederico Caldeira Knabben]

I think this is related to a bug in the iterate function, identified by Martin. He may take care of this on. Please confirm it with him first.

[Garry Yao]

Verified it has been fixed with #3304.
