Long-standing behaviour.  ".." in Cygwin and ".." in Windows can totally
disagree.  The path is always convert to absolute at this point in favor
of correct output.  There's also the additional restriction (though
not in this case) that relative Windows paths must not be longer than
MAX_PATH (260) chars.

I'm certainly open to patches to the underlying cygwin_conv_path
function to change the Windows path to relative if possible.
