This change won't be applied to stable.  It was initially intended 
to go to current only, see patch discussion here:

http://mailman.nginx.org/pipermail/nginx-devel/2011-December/001620.html

Actually, I even consider backing it out in current, as 
configuration in question is quite common and I don't really like 
both of the workarounds.  I don't like previous behaviour either, 
but the change seems to be more drastic than it was originally 
expected.
