As auctex launches pdftex with -interaction=nonstopmode, the
additional help messages displayed by TeX/LaTeX end up in the log file.

So it is only a matter here to fetch the messages from the log,
rather than using the specific ones incorporated into tex-buf.el

This mechanism is already in place where tex-bug.el does not have
an entry matching the message:

    ERROR: Extra \or.

    --- TeX said ---
    l.37 \iftrue\expandafter\fi\or
                                  
    --- HELP ---
    From the .log file...

    I'm ignoring this; it doesn't match any \if.

So, it should not be complicated.

The problem is to avoid in Plain TeX runs (or ConTeXt ? I am not familiar with it) to have the auctex generated error help go into LaTeX considerations which are not relevant to Plain TeX.
