[Bug 26943] New: copy command has different behaviour

http://bugs.winehq.org/show_bug.cgi?id=26943

Summary: copy command has different behaviour
           Product: Wine
           Version: 1.3.17
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

how to test:

- concatenate all txt files into files name alltxt.dat:

copy *.txt alltxt.dat

on Wine, it will ask for confirmation whether we want to overwrite or no, so
alltxt.dat will be the same as the last .txt copied.

on Windows, if alltxt.dat is not directory, it will create files named
alltxt.dat and if file alltxt.dat already exist, it will ask confirmation only
for the first time, and then it will concatenate all .txt files into
alltxt.dat. if alltxt.dat is a directory, it will copy .txt files under
alltxt.dat (separated file)
