Hash: SHA1

POSIX states that rename must fail with EINVAL if either argument ends in
'.' or '..' (after trailing slashes are stripped).  Cygwin 1.7 is
detecting this situation (which is a step up from 1.5 which did the rename
anyways), but sets errno to EBUSY instead of EINVAL.

$ mkdir d1 d2
$ mv -T d1/. d2 # the -T forces a raw rename("d1/.","d2")
mv: cannot move `d1/.' to `d2': Device or resource busy
