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.
