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.
