electric-pair-mode, it's not on by default.

But, for some reason, electric-indent-mode _is_ on by default,
at least in c++-ts-mode.

So this has nothing to do with tree-sitter IMO, it's just
electric-pair-mode doing its thing.

Why is it on by default?  A fair number of users don't like
this electricity, or prefer to have it toned down.  At least
this has been the  argument for not turning on electric-pair-mode
by default, which is a much less jarring mode IMO, and one which
would solve these problems.
