bug#73092: 31.0.50; Completion lists unbound variables with suffix - (e.g., rcirc-)

[Tassilo Horn]

It just occurred to me that variable completion with C-h v lists
non-existent variables with suffix -, e.g., rcirc-, Man-, Info-, info-,
etc.  When selecting one of those, the *Help* buffer just says

--8<---------------cut here---------------start------------->8---
rcirc- is void as a variable.

Not documented as a variable.
--8<---------------cut here---------------end--------------->8---

Yeah, that's correct, but why was it shown in the *Completions* then?

That happens with "emacs -Q" with emacs from git master.

Indeed, this is a known issue.
