Long-standing behaviour. ".." in Cygwin and ".." in Windows can totally
disagree. The path is always convert to absolute at this point in favor

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.
I am not understanding - it appears that "dot-dot" (..) is well defined by
POSIX:
The special filename dot-dot shall refer to the parent directory of its
predecessor directory. As a special case, in the root directory, dot-dot may
refer to the root directory itself.

so it would appears that ".." would be an acceptable return value in any case.
