Subject: [PATCH 5/5] pretty format %(trailers): add a "key_value_separator"
Date: Sat, 5 Dec 2020 02:39:18 +0100 [thread overview]
Message-ID: <20201205013918.18981-6-avarab@gmail.com> (raw)
In-Reply-To: <20201025212652.3003036-1-anders@0x63.nu>
As noted in a previous commit which added "keyonly" it's needlessly
hard to use the "log" machinery to produce machine-readable output for
%(trailers). with the combination of the existing "separator" and this
new "key_value_separator" this becomes trivial, as seen by the test
being added here.
