The way CVS modifies a file in the repository is to:
  - Make a temporary copy that includes the changes.  (Since CVS
    only reads the original file, the lack of write permission
    doesn't get in its way, but it needs write permission on the
    parent directory in order to create the copy.)

  - Rename the copy back over top of the original.  (Again, the
    write permission that applies is on the parent directory, NOT
    on the file itself.)
