在大型文档中，我一直使用基于 \marginnote{} 的注释命令。现在我注意到，marginnote 对间距有意外的影响，例如，它会导致章节的第一段缩进，而实际上不应该缩进。
原则上，我可以重新定义我的命令以始终添加\leavevmode，但这样我就必须追踪该命令的所有实例。另外，我的宏的行为会根据 而有所不同\ifvmode（请参阅 MWE）。我不能使用\marginpar，因为命令已在浮点中使用，并且由于某种原因，如果我根据 选择 marginpar 而不是 marginnote ，会导致“丢失浮点” \ifinner。
是否有某种方法可以换行、重新定义或替换 marginnote ，以使其不干扰段落缩进或间距，并且不需要更改整个文档中命令的调用方式？
有一些相关的问题，但它们最终都以需要改变整个文档的调用的方式得到了回答。

This text should not be indented.
The \verb|\unless\ifvmode\unskip|
was introduced to allow
\commentnote{Note(2)}
typesetting notes on separate lines without adding
\% characters at the end of each preceding line,
and in order to use \verb|\commentnote|
in vertical mode to create unmarked comments.
\commentnote{Note(3)}
\commentnote[\baselineskip]{Note (4)}
\commentnote[2\baselineskip]{Note (5)}
It is acceptable to use multiple notes before a paragraph.
Inserting \verb|\leavevmode| would cause spurious numbering.
\section{With \textbackslash leavevmode}
\@use@leavevmode@hacktrue
\commentnote{Foo}%
Using \verb|\leavevmode| leads to correct indentation,
but then requires manually removing newlines between
\verb|\commentnote| and paragraphs, and adding \%
characters at the end of each invocation.
\commentnote{Note(3)}%
\commentnote[\baselineskip]{Note (4)}%
\commentnote[2\baselineskip]{Note (5)}%
Furthermore, it leads to spurious numbering of out-of-paragraph notes.
