bug#23525: 11.89.1; Wired Behaviour of Quick View

[Qiang Yin]

Hi,

I don't know why offset can be negative, but it happends. As for an
example, please find the enclosed 3 files:

1. main.tex
2. sec-foo.tex
3. _region_.tex %% this is generated by AUCTeX

If I press 'C-c C-b' on "sec-foo.tex" it will produce the
"_region_.tex" and offset in this file is negative.

Cheers,
Qiang

\begin{document}
\begin{abstract}
Hello world.

Hello world.

\end{abstract}

\input{sec-foo}
