[latexrefman] a small typo in ``LaTeX2e: An unofficial reference manual''

[藤村行俊]

Dear sir,


Perhaps, I found a small typo in the following parts; there are two \begin{equation}s, the second of which is \end{equation}. 

—
8.9 equation


You should have no blank lines between \begin{equation} and \begin{equation}, or LaTeX will tell you that there is a missing dollar sign.
