Subject: [PATCH] CodingGuidelines: document // comments

From: Junio C Hamano <[email-masked]>
Date: Wed, 11 Feb 2026 11:17:48 -0800

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.
