Sorry, I ignored the list addresses, I always try to remove peoples' addresses.
(any suggestions for outlok 2003?)

Here is the question I am going with: If the path starts with \\?\ don't strip
the trailing slash, can this be cost effective or only cost more in that case?

So going through that so far, please correct me as needed, this is what I see:

In path_prefix_p we strip the trailing slash

Near the end on the path_conv::check we examine if it is s/^(.:)$/$1\\/

Not only that, but it is more of the only things that are likely to interact
with it are cygwin processes, why leave cygwin to do it.
