% markの処理
% 出力する柱は偶数ページでは\leftmark，奇数ページでは\rightmark．
% 見出し<HEAD>に\rightmarkがついていれば，\<HAED>markを\markrightに書き換える．
% \leftmarkならば\markbothを使う．
% \leftmark\rightmark両方の時は\markboth？
% 現れる全ての見出しのレベルよりも小さいレベルの見出しについては\<HEAD>markを空にする処理を入れる．
% 実際の出力：
%  yoko: 
%    左ページ（縦奇数ページ横偶数ページ）ではノンブルが左（2.6.1.c），なので<ノンブル><空き><柱>
%    空きが無駄に入らないように気をつける．（右寄せの場合は柱が空なら空きを入れない．）
%    \setbox..=して，幅が0か否かで判定する．
%    右ページでは逆になる．<柱><空き><ノンブル>
%    空きは柱文字で文字サイズ基準で計算する．
%    <ノンブル>も<柱>もi,ii,...はiが左になるようにする．
%    <柱>も<ノンブル>も<i中身><空き><ii中身><空き><iii中身>となる
%    ただし空きは無駄に入れない．左寄せの場合は<i中身>が空ならばその右の<空き>は入れない．
%    空かの判定は\protected@edefして\ifx\@emptyで判定する．
