为什么建议/etc/sudoers使用visudo命令编辑文件？这是该文件的示例：
## Sudoers allows particular users to run various commands as
## the root user, without needing the root password.
##
## Examples are provided at the bottom of the file for collections
## of related commands, which can then be delegated out to particular
## users or groups.
##
## This file must be edited with the 'visudo' command.
有什么特殊原因吗？
