Oops, my bad! new subrequests issued by
echo_location/echo_location_async in an eval block will not work at
all because ngx_eval's output filter cannot capture its
sub-sub-request's output.

Sorry about that. My fork of ngx_eval is currently limited to content
handlers and output filters that do not issue subrequests themselves.
