Enhancements:

A "version" command has been added. This has no effect on gameplay.

The text displayed by the "news" command has been updated.
A -l command-line option has been added. When this is given (with a

necessarily pretty ugly by modern standards. Encryption and
checksumming have been discarded - it's pointless to try

+Save and resume filenames are stripped of leading and trailing

A -r command-line option has been added. When it is given (with a file
path argument) it is functionally equivalent to a RESTORE command.
