The various shell-related modes set the environment variable "EMACS"
to "t".  This feature is useful for conditionalizing the behavior of
some programs.  Programs run with the compile package do not have this
variable set and should.

Perhaps Emacs should modify its own environment to add "EMACS=t" thus
ensuring that any subprocess will see it.
