[PATCH 05/12] diff: refactor output of incomplete line

From
Junio C Hamano <gitster@pobox.com>
Date
Nov 4, 2025, 02:09 UTC
Message-ID
<20251104020928.582199-6-gitster@pobox.com>
In-Reply-To
<20251104020928.582199-1-gitster@pobox.com>

Create a helper function that reacts to "\ No newline at the end of file" in preparation for unifying the incomplete line handling in the code path that handles xdiff output and the code path that bypasses xdiff and produces complete rewrite patch.
