bug#20773: 11.88.6; Preview fails on nested \include{} using \documentclass{sigplanconf}

[Alex Rozenshteyn]

Attempting to run `preview-document` on a file using
\documentclass{sigplanconf} (found here:
http://www.sigplan.org/sites/default/files/sigplanconf.cls)
led me to discover the following unpleasant behavior:

Imagine the document structure is as follows:

---     main.tex ---

\documentclass{sigplanconf}
\begin{document}
\input{formalism}
\end{document}

--- end main.tex ---

---     formalism.tex ---

\input{formalism_atranslation}

--- end formalism.tex ---

---     formalism_atranslation.tex ---

\section{A-Normal Form}

--- end formalism_atranslation.tex ---

When I run `preview-document` in "main.tex" (or in others if `TeX-master`
is set correctly.) I get one of two errors. On occasion, Preview-PDF2DSC
fails:

I tried to replicate this with other filenames, but have not had success
using "foo.tex" and "bar.tex", so I decided to send the actual
filenames.
