PROCEDURE AddBranch(delta: RCSDelta.T;
branch: RCSDelta.T;

RAISES {RCSError.E};
Add a new branch to the given delta.
The list of branches is maintained in sorted order. It is an error
to add a branch that is already present.
PROCEDURE ChangeBranch(delta, oldBranch, newBranch: RCSDelta.T)
RAISES {RCSError.E};
Changes a branch of the given delta to point to a different delta.
PROCEDURE DeleteBranch(delta: RCSDelta.T; branch: RCSDelta.T)
RAISES {RCSError.E};
Delete a branch from a delta. It is an error to attempt to delete a
non-existent branch.
