One more use for gnus-expert-user

[Teemu Likonen]

I'd like to suggest one more case where gnus-expert-user variable is
respected.

Details: Function gnus-agent-expire expires old articles from Gnus
agent's cache. When it founds directories (under ~/News/agent/) which
are no longer needed gnus-agent-expire (well, actually its helper
function) uses gnus-y-or-n-p function to ask whether the directory
should be deleted. User may want to unconditionally delete such
directories when she runs gnus-agent-expire automatically from some hook
(like gnus-exit-gnus-hook). The problem is that currently there is no
simple way to prevent the y-or-n question.

Currently I'm using a work-around with around-advice for gnus-y-or-n-p.
My advice, when activated, doesn't call the original gnus-y-or-n-p
function at all. It just unconditionally returns non-nil. I think that
this would be a good place to respect gnus-expert-user variable, though.

Here's a patch that implements my suggestion:
