Hi,

I have been thinking about this and I see a problem with the elpa way of
handling prefix auto-mode-alist associations. They go to a file that is not
a conffile. So, if that kind of conflicts appear it is not as easy to
handle as just editing one of the conffiles and commenting the undesired
association.
