I'm glad it's better now, since there aren't other comments yet I send another version, c-indentation-style had to be c-file-style. I also added a couple more variables and commented much more. I tested it with emacs24 and 23 on ubuntu 10.4 and everything seems to work as expected, but if anyone tries it and has problems let me know..
