Ha!  Back in Cornell I had a "DrSwindle" thing, which was a hack of
DrScheme that was needed since it was in the pre-module-days and
swindle was changing too much fro DrScheme to work.  One feature that
I was sneaking in in addition to making it work with Swindle was an
80-character line limit, which I've always wanted.

So, it would be nice if there was a general option to turn this on,
not only for the student languages.

(And from a non-teaching-language perspective, there are cases where
you want to change the indentation for some reason.  (*I* do that
too.))
