Relint on AUCTeX

[Arash Esbati]

Hi all,

I was curious so I ran relint (Elisp regexp mistake finder) on AUCTeX.
I case you don't know it, check here[1].  This is the result on main
AUCTeX installation directory:

In case the text above get mangled, the file is attached as well.  I've
briefly checked the results, they seem real to me, so no false
positives.  In case someone wants to fix these issue, please don't
hesitate :)

There also good news, no erros on style sub-directory.

Best, Arash
