BTW, this is hence related to Bug#22958 where we fixed it for the
specific case of `C-u` but we now need to fix it more generally.

Maybe we can treat all `overriding-terminal-local-map` as "transient" in
this respect, as in the patch below.

It's a bit risky, admittedly.  But it would be useful to know what
breaks when we do that, to get a better understanding about what the
condition above should really test.
