Isn't this going against what the documentation says? Minor modes are supposed 
to be preferences and the user may or may not want those modes turned on 
automatically.

It looks like the first mode line entry is treated as major mode and the 
subsequent ones as minor mode. Specifying this in the local variables section 
has the potential to set the major mode twice - first using set-auto-mode and 
then when the local variables section is processed.

Given the problem with bug-reference-mode and such, it makes sense to change 
the way settings are processed. 

I have some ideas on this, but WDYT? (Obviously, there is a question of 
compatibility with existing behavior, but that doesn't seem to be a big issue 
with other features).
