At least on XP cmd and others could not be run from a subdir below "...":

$ /bin/pwd
/tmp/...

$ cmd.exe /c cd
C:\cygwin\tmp

$ mkdir x

$ cd x

# /bin/pwd
/tmp/.../x

# cmd.exe /c cd
-bash: /cygdrive/c/WINDOWS/system32/cmd.exe: Not a directory


Same for "....", ".....", ....

Different path checking in win32api layer and ntdll layer ?

I would suggest to either quote or reject "..." in Cygwin.

Christian
