address@hidden: tex-mode: too many _ (underscores) interpreted as subscripts]

[Richard Stallman]

Would someone please investigate this bug report and DTRT?
Stefan made these changes, but he hasn't responded to
my mail about this, so I think it is time to look
for someone else.

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

Your bug report will be posted to the address@hidden mailing 
list.

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

The News file of CVS Emacs announces the following for TeX mode:

*** verbatim environments are now highlighted in courier by font-lock
and super/sub-scripts are made into super/sub-scripts.

At the moment, it considers too many underscores as subscript
commands. While it leaves \cite{blah99:_long_title} and
\verb+file_name+ alone, it displays the commands
\nolinkurl{file_name_with_underscore.txt} and
\url{file_name_with_underscore.txt} (both available with the hyperref
package, the last one also with url.sty) wrong, that is, the first
letter after an underscore in these commands is transformed into a
subscript.
