Subject: [PATCH 1/5] config.c: add a comment about why value=NULL is true
Date: Thu,  8 Apr 2021 15:34:25 +0200	[thread overview]
Message-ID: <patch-1.6-bd70181ffb-20210408T133125Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-0.6-0000000000-20210408T133125Z-avarab@gmail.com>

It's not very intuitive that git_parse_maybe_bool_text() would
consider NULL to be a true value. Add a small comment about it.

See a789ca70e7 (config: teach "git -c" to recognize an empty string,
2014-08-04) for the behavior of "git -c", but we'll end up here in
both the config file parsing and command-line parsing cases.
