        - fixed <rdar://problem/4036817> REGRESSION: ctrl-y broken when a line + carriage return cut

        * khtml/editing/htmlediting.h: Added insertTextRunWithoutNewlines.
        * khtml/editing/htmlediting.cpp:
        (khtml::InsertTextCommand::input): Added assertion to make sure strings with newlines don't get
        down to this level.
        (khtml::TypingCommand::insertText): Added. Takes the name of the old function, but is a new
        level that breaks runs into lines and inserts each one separately.
        (khtml::TypingCommand::insertTextRunWithoutNewlines): Renamed old insertText to this.

        * khtml/dom/dom_string.h: Made substring be a const member function.
        * khtml/dom/dom_string.cpp: (DOM::DOMString::substring): Made this const.

        * WebView.subproj/WebHTMLView.m:
        (-[WebHTMLView _deleteRange:killRing:prepend:smartDeleteOK:deletionAction:]): Merged _handleKillRing behavior
        into this function, since there's now a more-complicated way the startNewKillRingSequence boolean needs to
        be handled. Set the startNewKillRingSequence boolean after the entire process so changing the selection before
        and during the editing dosn't clear it. Also change "isTypingAction" parameter to "deletionAction" so we can
        handle forward delete with this method.
        (-[WebHTMLView _deleteSelection]): Pass deleteSelectionAction for action rather than NO for isTypingAction,
        which is the way to say the same thing using the new parameter.
        (-[WebHTMLView _deleteWithDirection:granularity:killRing:isTypingAction:]): Refactor to use the _deleteRange
        method above. Also calls _shouldDeleteRange: for the pre-existing selection case; not doing that before was
        a bug.
        (-[WebHTMLView deleteToMark:]): Pass deleteSelectionAction for action rather than NO for isTypingAction,
        which is the way to say the same thing using the new parameter.
