    Allow simple quoting of words in the dynamic debug control language.
    
    This allows more natural specification when using the control language
    to match against printk formats, e.g
    
    #echo -n 'format "Setting node for non-present cpu" +p' >
    	/mnt/debugfs/dynamic_debug/control
    
    instead of
    
    #echo -n 'format Setting\040node\040for\040non-present\040cpu +p' >
    	/mnt/debugfs/dynamic_debug/control
    
    Adjust the dynamic debug documention to describe that and provide a
    new example.  Adjust the existing examples in the documentation to
    reflect the current whitespace escaping behaviour when reading the
    control file.  Fix some minor documentation trailing whitespace.
