processing latex files without \\documentclass

[Robin Barker]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.1.1 (sparc-sun-solaris2.7, X toolkit)

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have some latex files which do not have \documentclass 
(or \documentstyle).  Typically these are one-liners,
e.g. dingofoo.tex:

    \PassOptionsToPackage{foo}{wombat}\input{dingo}

If I latex these files with no other latex file buffers 
all is OK.  However if another latex file buffer (e.g.
dingo.tex) is open and this is a "normal" latex file,
then this file (dingo.tex) is latex'ed instead of
dingofoo.tex.  This is really annoying!!

A workaround is to add a line '%\documentclass' in
dingofoo.tex but this is hardly elegant.
