os: Rename cannot move the file to a different disk drive

[zaz600]

go version go1.5.2 windows/386

After 92c5736 with MoveFileEx os.Rename("r:\1.txt", "z:\1.txt") on windows generate error:

The system cannot move the file to a different disk drive

When moving a file, the destination can be on a different file system or volume. If the destination is on another drive, you must set the MOVEFILE_COPY_ALLOWED flag in dwFlags.

So, syscall_windows.go Rename must be

func Rename(oldpath, newpath string) error {
    from, err := syscall.UTF16PtrFromString(oldpath)
    if err != nil {
        return err
    }
    to, err := syscall.UTF16PtrFromString(newpath)
    if err != nil {
        return err
    }
    return MoveFileEx(from, to, MOVEFILE_REPLACE_EXISTING|MOVEFILE_COPY_ALLOWED)
}

os.Rename doesn't move a file to a different drive on Unix either. I don't see a good reason to use MOVEFILE_COPY_ALLOWED; this is rename, not copy. According to the docs MOVEFILE_COPY_ALLOWED can leave you with two copies of the file, which is not desirable.

what's the status of this issue? I met the same error:
The system cannot move the file to a different disk drive

using go1.6 windows/amd64

@edisonrf, the status is "closed". See previous comments before it was closed.
