Wrap_predicate/4 not in text help

For some reason we often have some predicates missing from the text help even though they are present in the Web documentation.

I wonder if it would be a good idea to check programmatically that both documentation systems have the same list of predicates.

2 ?- help(wrap_predicate).
Warning: No help for wrap_predicate.
Warning: Use ?- apropos(query). to search for candidates.
