The underlying problem here is that people receive files from sources 
that use a case-insensitve filesystem.
This can happen to ANY type of file, so should we rewrite ALL our regexps?

Can you point to a single instance where doing a case-insensitve match 
as a fallback would be harmful?
Perhaps it would be easier to eliminate any such cases by explicitly 
adding them to auto-mode-alist.
