shutil.move does not behave as I expect when moving a symlink across filesystems. (This is when src itself is a symlink, not when it is a directory tree including symlinks.)

-If src is a symlink to file, rather than moving the symlink, it copies the contents of the file
-If src is a symlink to a directory, rather than moving the symlink, it copies the contents of the directory to a new directory
-If src is a dangling symlink, it errors out

Attached patch against the py3k branch adds tests for these cases and adds the expected behaviour, which is to recreate the symlink.

(I have encountered this on 2.6 - current SVN; it is probably in 2.5 as well but I have not confirmed.)
