Even though storing links to help buffers describing key bindings is
tempting, there is no way to recreate such buffers only based on the
key string, because keys are contextual.

In org-mode, C-h k C-a will describe org-beginning-of-line while in
other modes it will probably describe beginning-of-line.

So we cannot really write a proper handler for these links and the
user error is correct here.

I'm closing this bug report now.
