* MOVE.C - move internal command.

* History:

* 14-Dec-1998 (Eric Kohl)

* Started.

* 18-Jan-1999 (Eric Kohl)

* Unicode safe!

* Preliminary version!!!

* 20-Jan-1999 (Eric Kohl)

* Redirection safe!

* 27-Jan-1999 (Eric Kohl)

* Added help text ("/?").

* Added more error checks.

* 03-Feb-1999 (Eric Kohl)

* Added "/N" option.

* 30-Apr-2005 (Magnus Olsen <[email protected]>)

* Remove all hardcoded strings in En.rc

* 24-Jun-2005 (Brandon Turner <[email protected]>)

* Fixed bug to allow MS style wildcards + code clean up

* added /y and /-y
