bug#7646: rst.el uses fixed temporary files

[Glenn Morris]

Package: emacs
Severity: serious
Version: 23.2.91

(serious as in, should be fixed before 23.3)

rst.el uses fixed temporary file names of the form /tmp/filename,
in rst-compile-pdf-preview and rst-compile-slides-preview.

This was reported to Debian a year ago but never made its way here
(for some reason it was in the "python-docutils" package):
