This pair of braces is useful in a case like this:
We use \LaTeX{} to render math expression beautifully.
Without the brases, the space between "LaTeX" logo and "to" vanishes.

I personally dislike this braces, so customize `TeX-insert-braces' to
nil.  With this setting, the braces aren't inserted in AUCTeX.
