Subject: [PATCH 2/2] gnu: man-db: Use 'groff-minimal' at run time.
Date: Fri,  1 Dec 2017 10:58:44 +0100

This reduces the closure of man-db from 175 MiB to 97 MiB.

* gnu/packages/man.scm (man-db)[native-inputs]: Add GROFF.
[inputs]: Replace GROFF with GROFF-MINIMAL.
[arguments]: #:configure-flags now refers to GROFF-MINIMAL.
Add #:disallowed-references.
