Ignore value of EMACS, regardless of its value, if INSIDE_EMACS is set. According to the Emacs manual, EMACS should be set to "t" if INSIDE_EMACS is set: 36.2 Interactive Subshell Emacs sets the environment variable `INSIDE_EMACS' in the subshell to `VERSION,comint', where VERSION is the Emacs version (e.g., `24.1'). Programs can check this variable to determine whether they are running inside an Emacs subshell. (It also sets the `EMACS' environment variable to `t', if that environment variable is not already defined. However, this environment variable is deprecated; programs that use it should switch to using `INSIDE_EMACS' instead.) However, EMACS is set to a string containing the Emacs version in 24.3.50.1: $ env | grep EMACS EMACS=24.3.1 (term:0.96) INSIDE_EMACS=24.3.1,term:0.96 Instead of relying on a known value of EMACS when INSIDE_EMACS is set, just ignore the value of EMACS.
