/*
 *  COPY.C -- copy internal command.
 *
 *
 *  History:
 *
 *    01-Aug-98 (Rob Lake z63rrl@morgan.ucs.mun.ca)
 *        started
 *
 *    13-Aug-1998 (John P. Price)
 *        fixed memory leak problem in copy function.
 *        fixed copy function so it would work with wildcards in the source
 *
 *    13-Dec-1998 (Eric Kohl)
 *        Added COPY command to CMD.
 *
 *    26-Jan-1998 (Eric Kohl)
 *        Replaced CRT io functions by Win32 io functions.
 *
 *    27-Oct-1998 (Eric Kohl)
 *        Disabled prompting when used in batch mode.
 *
 *    03-Apr-2005 (Magnus Olsen <magnus@greatlord.com>)
 *        Remove all hardcode string to En.rc
 *
 *    13-Jul-2005 (Brandon Turner <turnerb7@msu.edu>)
 *        Rewrite to clean up copy and support wildcard.
 *
 *    20-Jul-2005 (Brandon Turner <turnerb7@msu.edu>)
 *        Add touch syntax.  "copy arp.exe+,,"
 *        Copy command is now completed.
