fileutils-4.1.9 rm command bug

Hi,
   First, thanks for your job.
   I think there is a bug in the file 'fileutils-4.1.9/src/remove.c', line 523, the function is 'is_empty_dir', you 'opendir' the 'dir', but not 'closedir' it. This does not cause any problems in most filesystems, but it does cause problems in filesystems that do the (!d_unhashed(entry)) check before they do the real deletion. you can't 'rm' directories in such filesystem with '-i' or '-ir' option.

       					Sincerely.
					He Zhenxing
