Description

The gzip documentation (​http://nginx.org/en/docs/http/ngx_http_gzip_module.html) does not warn about BREACH vulnerabilities opened-up by enabling gzip.

It should probably warn as well that text/html currenlyt cannot be disabled: AFAIU, this type is especially subsceptible to BREACH attachs (see #1083)
(compared to things like text/css, image/*). See #1083.
