Subject: [PATCH] doc: check-man: ignore backspace char
Date: Wed, 16 Oct 2019 08:18:23 +0000	[thread overview]
Message-ID: <20191016081823.23328-1-e@80x24.org> (raw)

man(1) on FreeBSD unconditionally emits backspace characters
for the bold effect despite its output being piped to awk(1).

Also tested with the man-db.nongnu.org version provided with
Debian (and presumably most other Linux systems).
