Description Ryosuke Niwa 2012-02-07 16:10:45 PST 
Press backspace inside the backspace in the following markup:
<div>hello</div>
<blockquote><br></blockquote>
<div>world</div>

WebKit generates:

<div>hello</div>
<div>world</div>

But it should be:
<div>hello</div>
<br>
<div>world</div>

or its variants instead.

It appears that we just need to generalize CompositeEditCommand::breakOutOfEmptyMailBlockquotedParagraph.

It turned out that the current behavior matches both IE and Opera. The only browser that exhibits the "desired" behavior is Firefox.

When you're at the beginning of an indented block and hit Backspace, browsers don't outdent, but word processors do.  (Tested in at least Google Docs and LibreOffice, pretty sure it's true in Word too.)  This matches the behavior of list items, and I think it's logical.  I think browsers should change to match word processors here, so backspace at the start of an indented block should outdent.  This is what my spec currently requires, although if implementers really don't want it, I can change it.
