Upgrade the Korn shell to the new upstream
The Korn shell 2020 project has ground to a halt and AT&T has reverted its
changes due to numerous unfixed performance regressions and bugs. The new
Korn shell project at github.com/ksh93/ksh has restarted development with a
focus on bug fixing and preserving Korn shell functionality.
