I think the problem is that the default value is not materialised — the
magic depends on whether the option was explicitly specified, the default
value does not correspond to any possible value of the command-line option.

I think the solution lies in making an explicit default value.  I'm
thinking of "-turn auto" being the default, and behaving as we do
currently if the option was not specified.  This is easier to explain,
gives a clearer mental image to the user, and has the added advantage of
being extensible -- people can hardly complain if the "auto" behaviour
changes between versions.

(I'm must resist the temptation of calling the value "magic".)
