    [docs] note that -g opts are implicitly negatable too
    
    Back in 2017, I made -g* options implicitly negatable, without
    realizing there was documentation that required updating.  Oops.
    Fixed, at last!
    
    
    for gcc/ChangeLog
    
            * doc/options.texi (option, RejectNegative): Mention that
            -g-started options are also implicitly negatable.
