        <rdar://problem/5543472> GoogleDocs: Safari hangs when creating a list from a particular selection

        Still need to fix similar issues with the other operations that iterate
        over selected paragraphs, like FormatBlock, Indent and Outdent (<rdar://problem/5658933>).

        * editing/IndentOutdentCommand.cpp:
        (WebCore::IndentOutdentCommand::indentRegion): Added a FIXME.
        * editing/IndentOutdentCommand.h: Removed an unused function.
        * editing/InsertListCommand.cpp:
        (WebCore::InsertListCommand::modifyRange):
        Renamed visibleStart to startOfSelection and visibleEnd to endOfSelection.
        Call the new selectionForParagraphIteration, which a) prevents operations like this
        one from being performed on a table that isn't fully selected (where the selection
        starts just before the table and ends inside it), and b) helps prevent paragraph
        iteration from going past the end of the selection.
        Call the new startOfNextParagraph, instead of using endOfParagraph(v).next(),
        since when v is in the last paragraph of the last cell of a table, that expression
        will return the position after the table, not the start of the next paragraph.
        * editing/htmlediting.cpp:
        (WebCore::enclosingListChild): Don't go above a table cell, so that list operations
        take effect inside the table cell where they are performed.
        (WebCore::selectionForParagraphIteration): Added, see above.
        (WebCore::indexForVisiblePosition): Moved from IndentOutdentCommand.cpp.
        * editing/htmlediting.h:
        * editing/visible_units.cpp:
        (WebCore::startOfNextParagraph): Added, see above.
        * editing/visible_units.h:
        * editing/TextIterator.h:
        (WebCore::TextIterator::exitNode): Added a FIXME.
