TeX mode: blinking on \{ .... \}

[Drew Burton]

We have just our production keyboarders to a new platform
and a much newer emacs version (19.30 [gulp] to 21.2, RedHat8}

A change that they have noticed is that in TeX mode previously
emacs would blink on TeX-quoted braces, i.e. \{ .... \}.

That is not the case in the current version.

I have searched around but have not found an answer simple enough
for me to change this behaviour.

I would greatly appreciate it if someone could help me.
