       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.
