    Check for presence of SHELL environment variable

    - POSIX states the SHELL environment variable "... shall represent a
      pathname of the user's preferred command language interpreter." As
      such, st should check for its presence when deciding what shell to
      use; just as HOME can be defined to override one's passwd-defined home
      directory, a user should also be able to override their passwd-defined
      shell using the SHELL environment variable.
