bash中的EMACS变量
今天翻看bash manual的时候猛然发现bash居然有一个 EMACS 变量，用来指示bash是否在Emacs的shell buffer中执行.
这种情况下bash会禁止行编辑功能。
关于EMACS变量的说明如下
EMACS If bash finds this variable in the environment when the shell
starts with value "t", it assumes that the shell is running in
an Emacs shell buffer and disables line editing.
