Oki, I  have worked a  little while with  this, and it _IS_  a problem
with the variables gnus-posting-style-alist and gnus-posting-styles.

In the first part (the 'Default') below, if I uncomment the ispell, yow,
spook and pgp lines, I end up with a header line saying 'Pgpid: turbo'.

So now, PGnus (v0.9?) is inserting my 'gnus-posting-styles' literally,
which it doesn't in the one that works (v0.84). There it sets the variable
I specified instead.

Which means, that when I use the '(ispell t)', it sets the variable
'turbo/process-ispell' to true instead.

When and why was this behaviour changed? (I'm not saying that it's
worse, I just have to rewrite some other hooks to take this into
account). Or is this a bug?
