    doc/groff.texi: Tweak \s discussion.
    Recast language regarding acceptable inputs to \sN in compatibility
    Regarding migration away from \sN, stop implying that \s(NN and \s[N]
    are the only options.
    Swap paragraph order to put the cross-reference to
    fractional-point-size-supporting escapes immediately the previous and
    before the detail about whether a point-size escape constitutes an input
