vim 为什么不断打印“indentexpr=”？

我在我的.vimrc中做了一些修改（安装一些插件，例如fzf，包括一些额外的配置等）。
继续使用vim，有一些我不喜欢的东西，indentexpr=的屏幕打印。当我准备启动vim或在项目中做一些其他操作（命令/导航）时，会发生这种情况。

第十四行：

set indentexpr

该命令将输出indentexpr的值：

indentexpr=         " value is empty
indentexpr=Foo()    " value is Foo()

因为你在你的vimrc中有这个命令，所以每次你的vimrc被源化时，这个值都会被输出。
至于为什么你经常得到那个字符串，也许是一个偶然的自动命令？
