Bash has used the INSIDE_EMACS variable to determine whether or not it's
running inside an emacs shell window since April, 2015, in response to

http://lists.gnu.org/archive/html/bug-bash/2015-03/msg00179.html

That came after bash-4.3 was released. There was another fix a year later
during the bash-4.4 release cycle to handle future emacs changes.

http://lists.gnu.org/archive/html/bug-bash/2016-04/msg00005.html

Eventually, I will remove the special handling of EMACS and just check
for INSIDE_EMACS. This is how the emacs documentation says to do it going
forward. It should be documented better in the bash documentation.
