bug#27088: 11.90; preview-latex fails for file names of certain length

[Ikumi Keita]

Remember to cover the basics.  Including a minimal LaTeX example
file exhibiting the problem might help.

Preview-latex fails if the length of the file name or the amount of the
document is sufficiently large.

[How to reproduce]
(0) Enable preview-latex.
(1) Save the attached file "preview-section-test.tex" in /tmp/ and open it.
(2) Type C-c C-p C-d and answer with "n" to "Cache preamble?" question.
(3) The ghostscript process hangs with error message "No bounding box"
and the process buffer is displayed.  Only the partial "\section{xxx}"
are covered by the expected images and rests remains icons of road
construction sign.  See the attached screenshot.

It is really strage to me that the length of the file name seems to be
related to this symptom.  If the *same* file is saved under the file
name "xxxxxxxxxxxxxxxxxx.tex" (18 x's), no errors occur and all
"\section{xxx}" are covered by suitable images after C-c C-p C-d.  But
the symptom occurs again if the file name is "xxxxxxxxxxxxxxxxxxx.tex"
(19 x's).

The amount of the document (or the number of pieces to be covered by
images in the buffer?) seems to be related, too.  If all the
"\section{xxx}" but the first "\section{abc}" are commented out in
"preview-section-test.tex", C-c C-p C-d runs without any problems.

Caching preamble also seems to be related.  If I answer with "y" to
"Cache preamble?" in "preview-section-test.tex", it doesn't exhibit any
problem.
