I'm still slightly reluctant, if the entry is meant to be a list then a 
single entry is valid and we're debating syntax.

On the other hand there *is* a potential cause for confusion - so at 
least an error will signal where the problem is. I think this is 
probably the right thing to do.

There is possibly also an issue with empty values and empty lists as well.

I'll look into it.
