Lars,
No, I don't use lexical bindings in this code. But, my point is that
the behavior of setq used to be to make variable special (i.e.
universaly accessible, like global, except it can be let-bound
temporarily), which it doesn't seem to do anymore. Is this change
intentional? I still didn't go over the entire changelog, but on the
surface of it, I didn't see this mentioned.
