Inefficient code in reftex-index.el

[Kim F. Storm]

I noticed the following code in reftex-index.el:

                    (condition-case nil (texmathp) (error nil))))
            (setq beg (car (match-data))
                  end (nth 1 (match-data)))

Using match-data like that seems inefficient.

I suggtest using match-beginning/match-end instead.
