vim won\'t turn autoindent off after \"set noai\"; have to resort to /bin/vi -c \'set noai\' --- --- ...or does it have something to do with smartindent?..
Unable to reproduce...
was triggered by some weird ("unrelated", as to me... but who knows) combo of settings in ~/.vimrc; was figured out, solved and long forgotten since. not sure if buggy copy exists somewhere still.
