Thanks for all the responses. Well that was very curious to me. Suppose I learn something every day.
On http://www.openbsd.org/faq/faq1.html all the links work. On the typo http://www.openbsd.org/faq//faq1.html an extra "faq/" is placed in _some links where it should not be. Such as http://www.openbsd.org/faq/donations.html Links to faqs and man pages appeared not to be affected. Thanks Again Moss
