I've not tracked down the culprit, but some new code in ActionView
that didn't require a :locals option now it does. Don't have time to
check whether it should, but we pass an empty :locals anyway in the
guides generator, just pushed that.
Now there's an issue with the credits template. We'll investigate that
one (follows a different path). As a temporary workaround you could
use the ONLY environment variable to generate only one guide, or
remove railties/guides/source/credits.erb.textile to generate
everything but that one and checkout later.
Now guides look weird. Something else has changed regarding
content_for or something (the guides generator itself uses ActionView)
and some stuff is inserted in a strange way into the layout.
I was wondering if we should remove the link to "Why’s (Poignant) Guide to Ruby" now that _Why is gone and the site is offline. Or maybe point the link to another working url (anyone knows where this guide can be found?)...
