    EEditorSelection: Fix unindentation
    
    When we have this text with indentation in composer:
    first_line
       a
    
       a
    
       X
    
    And we have cursor instead of X and we will try to unindent that line
    it will remove all after the first a. We have to mark the element that
    we want to unindent (with -x-evo-to-unindent class) to prevent
    webkit_node_is_equal_node return false positives when it will hit other empty
    lines like in this case.
