    libstdc++: Use ///< for inline documentation
    
    I noticed that some variables were misdocumented when using trailing
    comment for documentation.  I ran a search with a relatively simple
    regex[1] to look for any ///s following some code that did not have a <,
    and came up with these instances only.
    
    [1]: \s*([^  ]+\s*)+///[^<].*$
    
    libstdc++-v3/ChangeLog:
    
            * include/std/iostream: Use ///< for inline documentation.
            * include/std/limits: Likewise.
            * include/experimental/internet: Likewise.
