Spot on!

When transferring to the new server we forgot the old /erldoc redirect.

The newer http://erlang.org/doc/search works, and the caching in my browser
tricked me into believing that http://erlang.org/erldoc also still worked.

But it is fixed now.

Thank you first poster for pointing this out.
