I had a problem with spell-region not working very well on LaTex files
so I looked through spell.el to see if there was an easy way to pass
the -l flag to spell so that it would ignore LaTeX constructions.  No
such luck. So I hacked out the following modification to spell.el that
checks if the major-mode is either LaTeX-mode or TeX-mode, and if so,
passes the -l flag to spell. Disclaimer: I am not a Lisper nor do I
know much about the insides of emacs; hence, there might be a better
way to do this. If there is, please let me know.  The following is the
diff of my stuff and spell.el. We are running BSD 4.3 and GnuEmacs 18.47.
