(Info-read-node-name-2): Change to use `predicate' in the normal way.
(Info-read-node-name-1): Adjust uses accordingly.
* minibuffer.el (completion-table-with-context): Add support for `pred'.
(completion-table-with-terminator): Don't use complete-with-action
since we have to distinguish all three cases anyway.
