If you don't explicitly set the trust model, then gpg uses the trust
model that is saved in the trust db.  Using --tofu-policy doesn't use
the trust db (it only updates tofu.db), but --verify does.  Hence
after calling --tofu-policy, the trust mode is not saved, but after
calling --verify it is.

In general, it is better to set the trust-model in your gpg.conf file
and never set it on the command line if only because rebuilding the
trust db is very expensive for large key rings.

I suspect that there are other bugs of this sort, and I'm not sure it
is worth fixing.
