To be even more explicit about it, the regexp is extremely naive, and gives
the wrong results for a lot of common address formats -- not to mention for
even more uncommon formats. Do not use it, and do not try to modify it to
work!

Agree. In the case of user input validation, it might be ok to politely
inform the user that the address looks a bit funny, but refusing to work
with it will anger a user sooner or later.
