    diagnostics: use -Wformat-diag more consistently
    
    r10-1211 added various -Wformat-diag warnings about quoting in GCC
    diagnostic strings, but didn't change these two quoting warnings to use that
    flag as well.
    
    gcc/c-family/ChangeLog:
    
            * c-format.cc (flag_chars_t::validate): Control quoting warnings
            with -Wformat-diag.
