我有一个宏makeentry，我无法让它按预期运行。它非常简单，它获取先前输入的用户数据并对其进行格式化。但是，我无法让宏正确地尊重我的愿望parskips。vspaces发生了一些非常奇怪的交互，我肯定忽略了。不仅没有parskip发生，而且vspace位置也不对！
在本 mwe 中，我提供了两列比较，左边是宏格式的文本，右边是手动格式（和预期输出）的文本。

\name{Mount Baker}
\descr{Mount Baker, also known as Koma Kulshan or simply Kulshan, is a 10,781 ft active glacier-covered andesitic stratovolcano in the Cascade Volcanic Arc and the North Cascades of Washington in the United States. Mount Baker has the second-most thermally active crater in the Cascade Range after Mount St. Helens.}
\note{Mount Baker was well known to indigenous peoples of the Pacific Northwest. Indigenous names for the mountain include Koma Kulshan or Kulshan. In 1790, Manuel Quimper of the Spanish Navy set sail from Nootka, a temporary settlement on Vancouver Island, with orders to explore the newly discovered Strait of Juan de Fuca.}
