Subject: [PATCH v3] sequencer: rectify empty hint in call of require_clean_work_tree()
Date: Wed,  9 Aug 2023 19:15:31 +0200	[thread overview]
Message-ID: <20230809171531.2564829-1-oswald.buddenhagen@gmx.de> (raw)
In-Reply-To: <xmqqa5v2ehba.fsf@gitster.g>

The canonical way to represent "no error hint" is making it NULL, which
shortcuts the error() call altogether. This fixes the output by removing
the line which said just "error:", which would appear when starting a
rebase whose initial checkout worked fine despite a dirty worktree. This
was introduced by 97e1873 (rebase -i: rewrite complete_action() in C,
2018-08-28), which did a somewhat inaccurate conversion from shell.

To avoid that such bugs re-appear, test for the condition in
require_clean_work_tree().
