我正在尝试编写一个 sed 命令来替换文件中过多的空格。每个单词之间应该只有一个空格，但前导空格和制表符应该单独留下。所以文件：

     This is     an indented      paragraph. The   indentation   should not be changed.
This is the     second   line  of the    paragraph. 

会变成：

     This is an indented paragraph. The indentation should not be changed.
This is the second line of the paragraph.

我尝试过

/^[ \t]*/!s/[ \t]+/ /g

任何想法，将不胜感激。
