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.)
