When I said `tex-symb is slow', I opend texbook.tex, which is
available in CTAN, and I saw the bottom of the file (near L.28000).
In ordinary use, tex-symb.el is not so slow ;)

Thank you.  It works fine.  The speed of folding the symbol,
even at the bottom of texbook.tex, is up.

Hmm, I don't like this.  Actually, I do not fontify when
opening a LaTeX file ;)
