This is a reposting of the vi modelines fix.  Our notes system got 
confused and posted it to "net.unix-wizar" instead of "net.unix-wizards".

------------------------

With all the discussion of vi's modelines, I figured I'd post this here.
The diffs below show how to install a new on/off variable, "modelines",
which enables/disables interpretation of the modelines.  By default, it
is set to "nomodelines", and must be explicitly set by the user in order
to use modelines.
