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
| non-tabbable HTML editor: Shift+Tab after Tab on UL
- got "<ul><li id=\"target\">ul list item</li></ul>",
expected "<ul><ul><li id=\"target\">ul list item</li></ul></ul>"
* 7379 ERROR TEST-UNEXPECTED-FAIL

- got "ol list item",
expected "<ol><li id=\"target\">ol list item</li></ol>"
** editor/libeditor/html/tests/browserscope/test_richtext2.html **
The 15 tests that now pass result in 15 `FAIL' and 15 `UNEXPECTED_PASS'.

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.
Rationale: a command is supported if it can be converted to an internal Midas
command. `nsCommandManager::IsCommandSupported' might not be needed any more.
Corollary: document.queryCommandEnabled should return false on unsupported
commands without raising any exception.
Browserscope tests: +43 points = 258 failed tests...
* Q section: 0/48 => 42/48
42 tests used to fail (execution exception), now pass
* QE section: 36/46 => 37/46
garbage-1_TEXT-1 used to fail, now passes
In these two sections, a lot of tests that used to raise an exception now return
`false' (that's still a FAIL, but that's not the same kind of FAIL).
Other Browserscope tests are not affected by this patch.
The status of this test suite (currentStatus.js) has been updated accordingly.
