删除环境引入的缩进

Question

以下环境引入了缩进，我想避免这种情况。使用{%和}%没有帮助。

\documentclass[a4paper,12pt]{article}
\usepackage{xcolor}

\begin{document}

\NewDocumentEnvironment{wvPzz}{O{orange}mmo}
     {%
       \smallskip%
       \IfNoValueTF {#4}
           {%
              #2 \ #3 \hspace{\parindent}%
           }%
         {%
            #2 \ #3 \ (#4)%
            \smallskip \par%
         }%
       \color{#1}%
    }%
  {%
     \smallskip%
  }

Some Text Here

\begin{wvPzz}{aa}{bb}
  Some Text
\end{wvPzz}

Write Something

\begin{wvPzz}{aa}{bb}[cc]
  Some Text
\end{wvPzz}

Write Something

\begin{wvPzz}[blue]{aa}{bb}
  Some Text
\end{wvPzz}

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

\end{document}

不清楚您想要抑制哪些缩进，因为环境定义没有添加任何缩进，只有正​​常的段落缩进。但请注意，您应该在垂直模式下添加垂直跳过，因此前面是\par或空白行。我添加了\noindent所以（正如您在评论中而不是在问题中问的那样）aa与divisors

\documentclass[a4paper,12pt]{article}
\usepackage{xcolor}

\begin{document}

\NewDocumentEnvironment{wvPzz}{O{orange}mmo}
     {% par before smallskip
       \smallskip%
       \IfNoValueTF {#4}
           {%
% this is very weird, after #3, you get a word space, parindent???
% and thenpossibly a word space or paragraph break or possibly no space
% then the text from the body of the environment.
            \noindent  #2 \ #3 \hspace{\parindent}% 
           }%
         {%
% as above the behaviour after (#4) is somewhat variable
            #2 \ #3 \ (#4)%
% \par before \smallskip, not after
            \par\smallskip
         }%
       \color{#1}%
    }%
  {%
    % par (or blank line) before smallskip
    \par
     \smallskip%
  }

Some Text Here

\begin{wvPzz}{aa}{bb}

Write Something

\begin{wvPzz}[blue]{aa}{bb}
