Yeah, we need to remove that at some point.

You cannot rely on the fact that errorlevel is zero before entering
the batch file. See "setlocal /?", it suggests a more reliable
method.

What happens if extensions are disabled? Will arguments with "="
work? If not, we need to display a warning.
Anyway, "cmd /?" seems to imply that even if the extensions are
disabled in the Registry, one can enable them in an inferior shell by
invoking "cmd /e:on". If that is true, perhaps if you determine that
the extensions are disabled, you should reinvoke the batch file with
"cmd /e:on". If this works it's better than punting.
