In that last step, you failed to indicate if the path had a space or not.
ie, on Windows XP I get that behaviour now without needing to apply the

The vast majority of the patch is insignificant - it is either adding braces
where they are not necessary, or changing whitespace inappropriately (the
spaces you replaced are so the lines all line up regardless of the tab
width.)  It seems there is only one significant block in your patch, and its
not clear to me what the intent of the patch is - I admit I didn't apply it
and look at it in-place, but a couple of comments indicating exactly what
you are trying to do would be good, especially as I'm not aware of this
behaviour change from Win2K -> WinXP.

The existing code explicitly checks if it is the 9x or NT family, which your
patch no longer does.  It seems to me that Windows ME will also qualify -
although in general the strcmp for command.com will succeed, if an
alternative shell is installed on a ME box it will do the wrong thing.  If
you need to check anything more than the high-bit of GetVersion(), IMO it
should be replaced with GetVersionEx().
