Subject: [PATCH v4 01/13] substitute: Remove buffer handling from fetch.

From: Christopher Baines <[email-masked]>
Date: Sat, 16 Jan 2021 13:57:51 +0000

http-fetch does this, so just set the right option.

* guix/scripts/substitute.scm (fetch): Remove buffering code, and pass
 #:buffered? to http-fetch.
