#4 mv doesn't work

[Ilya "Voyager" Schurov]

mv command neither work nor returns error.

$ mkdir ~/wfs/wiki/test
$ cd ~/wfs/wiki/test
$ echo Hello > page.mw
$ mv page.mw hello.mw
$ cat hello.mw
cat: hello.mw: No such file or directory

I think we need 'mv' to use the default "move" feature of MediaWiki to preserve article's history.
