+	場合にのみ発動するようにしている．
+	\item 行の中身に水平ボックス$h''$が入ってくることもあるが，その場合は$h''$の中身までは参照しない．

+ \item[段階的な行送り調整]
+  既に述べたように，
+  「通常に組んだときの行間」$d$が\cs{lineskiplimit}より小さい場合，\TeX 標準では
+  行間は\cs{lineskip}となるのだった．
+  このとき行送りは「前の行の深さ」，「次の行の高さ」，\cs{lineskip}の3つの和になるわけだが，
+  場合によっては行送りを「\cs{baselineskip}の整数倍」などと切りのいい値に揃えたいという状況が
+  考えられなくもない．
+  
+  \Pkg{luatexja-adjust}パッケージでは，{\catcode`\<=12$d<\cs{lineskiplimit}$}のときに
+  行送りを\cs{baselineskip}の\Param{linestep\_factor}倍ずつ増減させて
+  \begin{quote}
+	行間が\cs{lineskip}以上となるような，
+	最小の$(1+k\cdot \Param{linestep\_factor})\cs{baselineskip}$（$k$は整数）の値
+  \end{quote}
+  とする機能を利用できるようにした．
+  \autoref{fig:linegap2}の(a)がこの機能を無効にした状況で，(b),~(c),~(d)が
+  それぞれ\Param{linestep\_factor}を0.25,~0.5,~1とした状況である．
+
+  なお，この機能は表組時(\cs{halign},~\cs{valign})には無効である．
+  \LaTeX における表組環境（tabular, arrayなど）では，\cs{baselineskip},~\cs{lineskip}はどちらも0に設定されているので
+  （代わりに各行に\cs{@arstrut}という支柱が入る）ために意味がないことと，
+  数式を内部で表組を使って組むalign環境などではかえって行間が不揃いになってしまうからである．
