I'm guessing it might help to make clear that `n'
will hide buffer *Disabled Command*, but it's not
killed and you can get back to it (e.g. to read it
again, follow the link, or whatever) using `C-x b'.

Another aid might be to not hide *Disabled Command*.

Another aid might be to also point/link to (emacs)
`Disabling', for more information about disabled
commands.  `i disabled command' takes you to that
node, and although the info there is mostly about
disabling (and enabling disabled) commands, it
also explains what a disabled command means etc.

I think the general point is that (1) showing
text that links somewhere, while not letting you
follow the link and (2) hiding that text if you
use `n' (or anything else), introduces unnecessary
confusion.

It's a bit as if the y/n dialog were ignorant of
the text being shown.  That text can invite a
quest for more info, but the simple y/n dialog
prevents that.  I can understand why/how a user
might think/say "Wtf?"

You may disagree that this dialog/info could or
should be improved, of course.
