My bad. I was pretty sure I'd had success with 'set foo ""' where
'hide' hadn't worked in the past.

Ack that. I'll personally keep linking to the wiki until the documentation

* is significantly better internally hyper-linked;
* has documentation targeted soley towards the open source nginx,
without having to skip to the end of each directive to check for "This
functionality is available as part of our commercial subscription
only";
* has useful pages such as IfIsEvil integrated into it.

I may be wrong about that third one still needing doing, but I
couldn't find IfIsEvil anywhere but the wiki. The presence of a
top-level pointer on each wiki page to http://nginx.org/en/docs/ is
pretty useless, too - it needs to point to the appropriate place in
the docs to get people to start using them.

Didn't you guys pick up several millions a while ago, which was
announced as being somewhat earmarked for improving documentation? :-)
