I don't know because I'm using an old version. The great thing about Emacs
is that if you can't customize it using variables, you can always go to
the source.

Since my version is old I'm just guessing.

I see that it runs the command tex-insert-braces. Try that command
with M-x tex-insert-braces in case the binding has been changed.

You can see the definition with "C-hf" (describe-function) and visit
the source.

Thanks, that's a good start. I looked at the tex-insert-braces definition 
in tex-mode.el and this is all I've found:

(define-skeleton tex-insert-braces
  "Make a pair of braces and be poised to type inside of them."
  nil
  ?\{ _ ?})


I don't know lisp so that's very cryptic for me. I don't know what might 
trigger it to insert a new line when doing nested C-c {

I tried `C-h w' and typed in `tex-insert-braces' on prompt and the
message line says `tex-insert-braces is not on any key' --- That might
be just because of some of my customization (or lack of it thereof).

You may try on your system.

Btw, `C-h k C-h w' says

Hope that helps,
