大きな本では、段落の間に不必要な空行が入ることがよくあります。よくある原因は、段落が最終行にぴったり収まり、その後に脚注や文末脚注に関する指示が続くことです。
私の MWE は、再現が難しい動作のため、少し太っています。正確なレイアウトを変更するものを変更すると、問題が解消されるようです。以下は私の LaTeX コードです (これは XSLT によって生成され、人間が読むことを意図したものではなく、サイズを小さくするためにさらに手動で切り詰めました。申し訳ありません)。

A man is sitting at a desk and typing.
He is writing in a language that no one on earth speaks.
Without long hours of study,
even someone who understood the language would be hard
pressed to read his work and understand his precise intent.
Sometimes, he stops and thinks, or draws pictures on
a piece of paper or whiteboard, or stops to sleep, eat, or
meet with others, but he always returns to typing.
Hours turn into days, days into weeks,
weeks into months, and perhaps even months into
years before the man stands up and declares he is \enquote{done.}%
\par
Done with what?
What has he created?%
\par
What he has created is a computer program,
but that explains little about what it is or even where
it exists.
At the physical level,
a computer program is usually a microscopic pattern of either electricity or
magnetism.
It may flow as whirling fields of electromagnetism from one form into another,
and be endlessly duplicated and replicated across many different
machines.
It often exists in a great many places---indeed, it only
really ceases to exist if all those copies are tracked down and obliterated
(and modern programmers generally keep an astounding number of copies of each program).%
\par
What, then, is computer programming, really?
Computer programming can be described in a number of ways,
but I will give you a factually accurate description of the
profession that you have not heard before: \begin{quote}\textbf{Computer programming is the act of designing complex patterns
of energy that affect the world.}\end{quote} I chose the two clauses in that definition carefully.
Although there are other professions that produce patterns
of energy (such as broadcasting electromagnetic FM waves),
they are not acts of designed energy like computer programming,
where every ultra-microscopic electric, magnetic, or chemical state is a result of human decision. \label{id265852}The composer Edgard Var\`{e}se declared that \label{id265846}\enquote{Music is organized sound.} and I am making an analogous declaration: software is organized energy. \label{id265842}\setcounter{pagenote}{0}\pagenote[id265852]{{\itshape The composer Edgard Var\`{e}se declared that \enquote{Music is organized sound.}}: \protect \cite[]{j:OrganizedSound}.
And though an infinite amount of music can be composed
with a twelve-note scale,
software has reduced this to the logical extreme,
generating its infinite variations from only two notes.
Var\`{e}se also said that \enquote{Our musical alphabet is poor and illogical} \protect \cite[]{b:ClassicEssaysMusic},
which is perhaps also analogous to the situation with software,
or maybe the mere longing of all creators for better tools.}\ignorespaces %%
And though much software operates nearly invisibly,
software affects the world in increasingly direct ways;%
\footnote{\label{FN:id265788}\label{FN:id265811}Turing Award winner Butler Lampson asserts the three historical phases of computers to date are:
modeling the world, connecting people, and engaging with the physical world.
The progression of these phases represents increasingly direct effects on the world.}
even in the early days when software might produce merely a
number that a human would read,
some of those numbers helped create the first atomic bomb,
so the size of software's effect on the world cannot be inferred
from how directly the software manipulates the world.

LaTeX は改行ごとにスペースを認識します。特に、1 行目と 2 行目の間にはスペースがあります。この後の命令は aux-file に書き込む必要があるため、「whatsit」ノードを挿入します。したがって、1 行目の末尾のスペースは「破棄可能」であり、段落の末尾で破棄されますが、その後に破棄不可能な「whatsit」が続くため、破棄できません。この結果、段落の末尾にスペースが残り、TeX はこれをブレークポイントとして使用することがあります。(詳細については、演習 14.12 以降の TeXbook を参照してください)
この問題はスペースを追加しないことで回避できます。したがって、テキストの後に が含まれる行が続く場合は\pagenote、%行末に を追加します。
