[PATCH] cmd: copy: "Path not found" error

[Dmitry Potapov]

When I tried to copy an old file to a new non-existing file, the copy
command failed with the "Path not found" error:

Z:\tmp> copy oldfile newfile
Path not found

It turns out that the copy command erroneously interpreted a not existing
destination file as an existing directory and failed when tried to copy
into it.

The bug was introduced in commit a766ba057061e669f8a8bbad19287f46d6391bae
> Author: Jason Edmeades

> cmd: Add support for wildcards in copy.

Affected Wine releases are 0.9.43 and up to 0.9.46
