Thanks. A related issue: 2.5.0's NEWS has:
o options(device = ) now accepts a function object as well as
the name of a function.
(For some reason, I had thought this was true all along, but in any
case) This means that it's now reasonable to do

But then I get (iff there is no device open)

Error in match(x, table, nomatch = 0) : 'match' requires vector arguments
because dev.interactive() doesn't know about the change yet.
dev.interactive() cannot really do anything useful in this case, but
an error seems too harsh (especially since example(glm) doesn't even
have any graphics).
