Turning off one time signature in 2.1.25

[Reuben Thomas]

I want to do something very simple: change the time signature without
anything appearing. I looked over the list archive, but I can't find the
solution. In particular, I don't want a transparent time signature; I want
no space taken.

I found various proposed solutions, and I tried inserting lines like

\override Score.TimeSignature #'style = \turnOff

and

\set Staff.TimeSignature = \turnOff

just before the time signature in question, but to no avail: the time
signature remains there. Perhaps I'm misunderstanding something about
contexts? The bit of my file in question looks something like this:

            \new Staff {
                \notes{
                    \clef "bass"
                    \key d\major
                    d2. d4 | d2. d4 | d2 d2 | d2 d2 |
                    ...
                    d2 g,4 b,4 | a,1 | d1 | g,1 ~ | g,2 d2 |
\override Score.TimeSignature #'style = \turnOff
%\set Staff.TimeSignature = \turnOff
                    g,1 | \time 8/4 d\breve \bar "||"
                }

As you can see, the reason I want an invisible time signature is because I
have a single bar with a breve in at the end of a movement.
