Subject: [PATCH v5] doc: fix the max number of git show-branches shown

From: "Rikita Ishikawa via GitGitGadget" <[email-masked]>
Date: Mon, 08 Jul 2024 13:07:59 +0000

From: Rikita Ishikawa <[email-masked]>

The number to be displayed is calculated by the
following defined in object.h.

    #define REV_SHIFT        2
    #define MAX_REVS        (FLAG_BITS - REV_SHIFT)

FLAG_BITS is currently 28, so 26 is the correct
number.
