Ah, sorry; I don't know why I thought t was allowed.  But the code I was
commenting on would fail with nil too, as I said, so the point remains.

While reading further I also see that we already have
`safe-local-variable-values' for the case where particular values need to
be marked as safe, which certainly satisfies the stated desire to allow
one additional value for a variable without the `lambda' trickery. 
Perhaps the `safe-file-function' property would nonetheless be useful to
avoid having to add many different things to s-l-v-v.
