• Added os.setalias() for setting a doskey alias without needing to invoke the doskey.exe program.
• Fixed a case where match descriptions could be displayed with incorrect padding and truncation (regression introduced in v1.6.6).
• Lua debugging enhancements:
  • Changed the built-in embedded scripts to include debug info, which allows some Lua error messages to be more useful for troubleshooting.
  • Added srcmap command in the Lua debugger to override where to find source files.
