    view: handle cases where indent-width and tab-width match
    
    Currently, indent-width is set to -1 to set a behavior that it should
    inherit the value of tab-width. However, if the value actually matches
    tab-width, a different behavior is applied for the insertion of tabs.
    
    This handles that scenario when indenting and lines and inserting tabs.
