Supplementary note for Jean: This treatment ends up with giving
special syntax (in terms of Elisp) rule to the both ends of
{{foo}
, which leads to incorrect hehavior of `show-paren-mode' you are talking
about. The next paragraph discusses the effect of that special syntax.

Hmm, I didn't know that \hyperref accepts these two different usage.
It's rather unordinary, isn't it? If AUCTeX is to support both usage, I
suppose that we have to implement it as a highly exceptional case.
