Actually for me this is not the issue. The issue, for me, is the
inability of emacs to understand as a tex file something that is
plainly and without any doubt a tex file. This is a file likely
riddled with latex commands, and which has the "tex" extension.
Surely this has been the format of tex files long before emacs even
existed, if such a time ever existed. Simply because this file has a
comment line with a particular format should not really cause emacs
to automatically think of it s a postscript file, when nothing else
about the file indicates that it is postscript.
From the point of view of the user of the program (hence the "I" in
this paragraph is the user), I have a tex file, and it is a valid tex
file, and it should be opened as a tex file. I neither know nor care
what the format specification of PS files is, and neither should I.
What I was trying to say in my post was exactly this simple fact
that, given the extension of the file, emacs should not consider it
automatically as a postscript file, in sort the heuristic it uses to
determine what language the file is from is flawed.
My second point was that given the infinite extensibility of emacs it
should be both doable and easy to tell it to treat all files with
extension "tex" as tex files.
