cmd: Fix a usage message: the % must be doubled for FOR variables. (resend)

[Francois Gouget]

The usage message was in fact documenting an old Wine bug.

The attempt did not apply, probably because I had other changes in my 
tree. Hopefully this one will work.


I'm reluctant to change messages at this stage as it's going to cause 
fuzzying of the translations, but given that this message is plain wrong 
I think it's warranted. To verify this, try out the following commands:

$ echo 'for %%i in (1 2) do echo %%i' >foo.cmd; wine cmd /c 
foo.cmd

C:\>for %i in (1 2) do echo %i 
1
2
$ echo 'for %%i in (1 2) do echo %i' >foo.cmd; wine cmd /c foo.cmd

C:\>for %i in (1 2) do echo i 
i
i
$ echo 'for %i in (1 2) do echo %i' >foo.cmd; wine cmd /c foo.cmd

C:\>for i 
Syntax error
$ wine cmd
Wine CMD version 5.1.2600 (1.6-rc4)

C:\>for %i in (1 2) do echo %i
1
2
