    multiflags: fix doc warning properly
    
    Rather than a dubious fix for a dubious warning, namely adding a
    period after a parenthesized @xref because the warning demands it, use
    @pxref that is meant for exactly this case.  Thanks to Joseph Myers
    for introducing me to it.
    
    
    for  gcc/ChangeLog
    
            * doc/invoke.texi (multiflags): Drop extraneous period, use
            @pxref instead.
