Subject: [PATCH v4 2/4] send-pack: properly use parse_options() API for usage string
Date: Mon, 13 Sep 2021 02:13:20 +0200	[thread overview]
Message-ID: <patch-v4-2.4-f10ff775c69-20210912T235347Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v4-0.4-00000000000-20210912T235347Z-avarab@gmail.com>

When "send-pack" was changed to use the parse_options() API in
068c77a5189 (builtin/send-pack.c: use parse_options API, 2015-08-19)
it was made to use one very long line, instead it should split them up
with newlines.

Furthermore we were including an inline explanation that you couldn't
combine "--all" and "<ref>", but unlike in the "blame" case this was
not preceded by an empty string.

Let's instead show that --all and <ref> can't be combined in the the
usual language of the usage syntax instead. We can make it clear that
one of the two options "--foo" and "--bar" is mandatory, but that the
two are mutually exclusive by referring to them as "( --foo | --bar
)".
