i always tend to oversimplify things, and i like to avoid
autocommands and plugins -- what i would do is add a variable to
your .vimrc that would set or not the ff setting autocommand
depending on the value of the variable -- then i would make two
copies of all my vim start scripts, one to allow the
autocommand, the other to force the ff setting you want
