[PATCH 1/5 v2] cmd/tests: Add tests for the magic environment variables.

[Francois Gouget]

Signed-off-by: Francois Gouget <fgouget at codeweavers.com>
---
v2:
- Some locales add the day-of-week before the date. Adjust the tests 
  accordingly.
- Add more for %cd%, %errorlevel%, defined, tests.
- Compare date /t with %date%, and time /t with %time%.
- Modify the tests so they work with @todo_wine at .
