The following functions need documentation:
hook_form_alter()
hook_form_validate_alter()
hook_form_execute_alter()


Additionally, I've noticed that the following hook documentation needs
to be updated to use the new Forms API for 4.7:
hook_block()
hook_settings()
hook_user()


This isn't meant to be a complete list, just a starting point. Please
add any other hooks you may find.
