B> most likely caused by missing recommended package emacs-el.

Dear bug-gnu-emacs, I got an idea for [email-masked]:
Show the same thing no matter if the user has the .els installed or not.
And when he clicks on it have a message: "Source code not available
because you don't have the .els installed."

Or next to the link have "(source code not installed)" etc. next to the
link so he knows before he clicks it.

Currently he has no clue that source code is actually available,
thus defeating the whole Free Software Movement!
