That accept-process-output is done after sending gpg the text that we
want to encrypy/decrypt.  Gpg calls pinentry *before* accepting the
text.

BTW, for anyone who would like to test out your ideas on this problem,
here is a recipe:

1. $ killall gpg-agent; eval `gpg-agent --daemon`;
2. $ emacs
3. [Put some text in the region]
4. M-x pgg-sign-region

The two behaviors of pinentry can be observed to depend on whether you
are on the console or in X.
