将标点符号置于框后

Question

在本文档中，我认为句号与盒子底部水平对齐看起来会更好。也许它也应该更粗一些。

如果您认为对齐是正确的，请说出来。

编辑：我的编辑同意@egreg的观点。我将保留句号。

\documentclass{article}

\usepackage{xparse}

\DeclareDocumentCommand\gc{ s m }%
{%
   \IfBooleanTF {#1}%
     {%
     \begin{center}
     \framebox{#2} \ .
     \end{center}
     }
     {%
     \begin{center}
     \framebox{#2}
     \end{center}
     }
}

\begin{document}
It's important to know how to do the calculation, but also important
to know how to ask someone to do it for you --- in this case, Google
(or Bing).
Enter
\gc{
12 miles per gallon in gallons per 10000 miles  
}
in the search box. Google tells you
\gc*{
12 miles per gallon = 833.333333 US gallons per (10 000 miles)
}

\end{document}

正如 egreg 告诉你的那样，你想要的东西在印刷上是错误的。但是，如果你坚持，

\DeclareDocumentCommand\gc{ s m }%
{%
   \IfBooleanTF {#1}%
     {%
     \begin{center}
     \raisebox{\depth}{\framebox{#2}} \ .
     \end{center}
     }
     {%
     \begin{center}
     \framebox{#2}
     \end{center}
     }
}
