Well, you're on the right track, as you certainly want
set tw=0
set noai
at the bottom of your vimrc. Your filetype settings might be
changing your indentation, so you might dig around for a line
something like
filetype indent on
which tells Vim to indent based on the detected filetype.
To track down who's monkeying with your settings, you can use:
:verbose set tw?
:verbose set ai?
You can also use
:scriptnames
The combo of knowing which script hosed your setting and when
that script was called should help you track down the trouble-maker.
You can read more at
:help :filetype
:help :verbose
:help :scriptnames
Hope this helps,
