"%%% TeX-master: t" appears twice.

[Hongyi Zhao]

Hi here,

I noticed the following auto-generated LaTeX comment code at the end of my file:

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% TeX-master: t
%%% End:

But I want to know why there are two duplicate lines, aka, "%%% TeX-master: t"?

Regards,
Zhao
