Fabien Cazenave e9ca41c695 Bug 677752 - [contentEditable] indent and justify* fail on editable nodes that have only one child; r=ehsan
Issue #1: indent/justify* can create non-valid fragments.
When applying a block-level formatting to a text node, Gecko creates a div or
blockquote block around the text node and sets the corresponding "align" or
"style" attribute. This patch checks that the active editing host can contain
such a block-level element.

Issue #2: indent/justify* can modify the active editing host.
On the first child of the editable element, the selection is extended outside of
the active editing host -- which causes a few issues for our test cases.
In this patch, this issue is "solved" by modifying
`nsHTMLEditRules::GetPromotedPoint' for block-level operations.


** About the tests **

Sorry for the long explanation but I prefer to be as sharp as possible when I
have to modify existing unit tests.

This patch raises 34 unit test "failures" which are improvements.
Two test files are concerned and have been modified accordingly:
  * test_htmleditor_keyevent_handling
  * test_richtext2.html

One test has been clarified (no real modification):
  * test_bug414526.html

Of course, a specific unit test has been added, see `test_bug677752.html'.


** editor/libeditor/html/tests/test_htmleditor_keyevent_handling.html **
Outdenting now works properly, which results in 4 `FAIL'.

  * 7372 ERROR TEST-UNEXPECTED-FAIL

** editor/libeditor/html/tests/browserscope/test_richtext2.html **
The 15 tests that now pass result in 15 `FAIL' and 15 `UNEXPECTED_PASS'.

** editor/libeditor/html/tests/test_bug414526.html **
This test has been clarified to get more explicit report messages -- the test
themselves haven't been changed. A `todo_is' test has been added.
This test is the one that shows that `IsNodeInActiveEditor' can't be modified,
and that limiting the range promotion for block-level operations is preferrable.
