[PATCH] CodingGuidelines: document // comments

From: Junio C Hamano <gitster@pobox.com>
Date: Feb 11, 2026, 19:17 UTC
Message-ID: <xmqqikc3t7hf.fsf@gitster.g>

We do not use // comments in our C code, which is implied by the description of multi-line comment rule and its examples, but is not explicitly spelled out. Spell it out.
