`describe-function` sometimes gives incorrect information about when certain functions were first introduced. NEWS.unknown can be used to fix some problems but it only works in one direction and is unable to help when a function name appears too early.

A robust solution would be to make NEWS* use a mark-up like @function{some-name} instead of just 'some-name' but meanwhile, here is a simple patch that replaces NEWS.unknown with a more structured file. This fixes the case for `always`.
