Sorry for the late reply. I meant to do that yesterday but SVN was down.
I've looked into SVN history and the /cw dates back to 2001 when I
submitted the first version of a PSRenderer (before I became a committer).
I can't recall why I've added that. If everything still works without it,
then I guess it wasn't necessary and it was fine to remove it.
