Summary: batfile executed with wcmd fails if bat comand args have
                    paths ending in \
           Product: Wine
           Version: 0.9.17.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-tools
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

executing bat files where command parametes ends in \ fails

example moving file from one directory to the other:

create a scratch dir test (mdir test)
create a dummyfile (touch dummyfile.txt)
create a bat file (test.bat) containing the sole line:
move .\dummyfile.txt .\test\
runnit with:
wcmd /c test.bat
this will generate an "Access denied" error

remove the trailing "" on the directory test in the bat file and it will work

This error stops Saga of Ryzom being able to do auto patching, since it calls 
a bat file to move the new patch files into position and then restart itself
