XPD-WikiImprovedHyperlinks

The WikiClassic? version has a very strict view of hyperlinks, our script uses the following regular expression:

 $LinkPattern? = '([A-Z?]+(\-|[a-z0-9]+))([A-Z0?-9][a-z0-9]*)+';

This pattern is much more forgiving allowing words with hyphens, trailing capitals etc. As I had problems using the \b word boundary expression I had to introduce some code to prevent words forming that didn't begin on valid boundaries --TimM

We tend to use the hyphen as a sort of namespace.

The following are hyperlink tests:
