help - how do I turn off auto-indenting?

[jalvesvim]

For some reason autoindent go turned on again with Vim 7.0.

In earlier versions, I disabled it via "set textwidth=0" at the bottom
of my .vimrc, however, now, somehow this setting is being overwritten
somewhere, and textwidth is being set to something else (i.e 78 last
I checked).

How do I fix this?

Thanks.
