See e.g. vc-steal-lock. It's only used in vc-next-action.

If you don't use RCS in a multi-level environment, same as Eli, and 
nobody else does, we don't really need that locking feature, and so we 
don't need vc-next-action to "steal the lock" as a separate step. We 
don't need that function, and we don't need the `steal-lock' backend 
command.

If RCS demands that a file is locked to the current user before 
committing (I'm not sure), vc-rcs-checkin could do that.
