In wine/programs/cmd/tests there are 2 files :
+ test_builtins.cmd
+ test_builtins.cmd.exp

The first one is a kind of .bat on windows.
The wine cmd read line after line and execute it.

Then, the output is compared to the content of the second one.

I know the title of my patch may be unclear but it's really what windows 
cmd does :
cmd_prompt>echo a at space@
a

A space is added at the end of the line.
That @space@ is added in the test_builtins.cmd.exp

However, to extend tests, I added several lines in test_builtins.cmd 
with terminating spaces.
There, AJ warned me that git will ignore them as they are trailing spaces.
He tolds me to find a way to add these spaces.
I first tried ^z (an ASCII char meaning substitute) but he replied me it 
is considered as a new line on windows.
He advise me then to use, as in test_bultins.cmd.exp "@space@"

And that's why I have to "parse" the input cmd_data to find and replace 
@space@ occurences with "real" spaces.

I hope it's now clearer.
