I was writing a specification document needing numbered paragraphs. I implemented it like this:
\reversemarginpar
\newcommand\countparagraphs{
\everypar{%
\addtocounter{paragraph}{1}%
\marginpar{\hfill\ttfamily\bfseries\arabic{paragraph} \textsection}%
}
}
\makeatletter
\@addtoreset{paragraph}{section}
\makeatother
\newcommand\CountedSection[1]{\section{#1}\countparagraphs}
\setlength{\parindent}{0pt}
\setlength{\parskip}{0.7\baselineskip}
This however gives odd page breaks. Specifically, the page breaks several paragraphs before the end of the page.
I determined that this was caused by the use of \marginpar{...} and replaced it with
\hspace{-4em}\makebox[3em][r]{...}\hspace{1em}
which solves the problem.
I would however like to know what really happened here. Why does \marginpar affect the page breaking?
Here's a MWE:
\documentclass[a4paper]{article}
\usepackage[margin=3cm]{geometry}
\newcommand\countparagraphs{\everypar{\marginpar{!}}}
\newcommand\CountedSection[1]{\section{#1}\countparagraphs}
