This mismatch of modeline identifiers is ABSOLUTELY YOUR 
PROBLEM!!!!!!!!!!!!!!!!!!!!!

Until you fix your config to have EXACTLY THE SAME string in both places 
IT WILL NOT WORK!!!!!!!!

Did I get your attention? So calm down, mix yourself a strong drink and 
try it again in the morning. Linux is all about things exactly matching. 
That includes Capitalization and special characters. Linux also reserves 
some special characters ($%*@) for special functions and they are NOT 
ALLOWED in names (Like the name of your modeline). Dash ( - ) and 
underscore ( _ ) are allowed.
