Re: cygpath -w converts relative paths to absolute windows paths

I've found that `cygpath --windows '../` will give back an absolute windows path.
".." is a special path, that can't be safely converted.
How is the special meaning of ".." so much different in Windows than in
Cygwin/Linux/POSIX that it could not be mapped?
Things like dir .., cd .., type ..\sub\file all work comparably.
Comparable? May be. Predictable?
I don't know what __DIR__ is supposed to mean in PHP. Anyway, handling ".." is not predictable even within Linux/Cygwin, you could see something like:
> ls dir1/file
> cd dir2
> ls ../dir1/file
No such file or directory

(if dir2 is a link), or can have surprising effects of cd vs. cd -P.
I don't see how that should exclude ".." from being transformed to ".." by cygpath -w, even if the result may be somewhat unexpected in some border cases (which I haven't seen yet).
