This is a merge of Blink <a href="http://trac.webkit.org/projects/webkit/changeset/176735">r176735</a>:
https://codereview.chromium.org/349143002
Test: editing/execCommand/indent-no-visible-contents-crash.html
* editing/CompositeEditCommand.cpp:
(WebCore::CompositeEditCommand::moveParagraphWithClones):
Sometimes callers of this method will pass null startOfParagraphToMove || endOfParagraphToMove,
hence check them before proceeding.
LayoutTests:
* editing/execCommand/indent-no-visible-contents-crash-expected.txt: Added.
* editing/execCommand/indent-no-visible-contents-crash.html: Added.</pre>
