    Improve error handling for Japanese users
    
    * tex-buf.el (TeX-help-error): Use number based condition to
    detect whether the search over `TeX-error-description-list'
    comes to its last element.  Comparison with a literal string
    breaks when tex-jp.el installs Japanese help messages into
    `TeX-error-description-list'.
