From 3a2ebaebc76b302629a5789696d67a0ce2c4378e Mon Sep 17 00:00:00 2001 From: Glen Choo Date: Wed, 1 Feb 2023 10:40:41 +0800 Subject: [PATCH] docs: document zero bits in index "mode" Documentation/gitformat-index.txt describes the "mode" as 32 bits, but only documents 16 bits. Document the missing 16 bits and specify that 'unused' bits must be zero.
