Message-ID: <pull.1757.v3.git.1720318768439.gitgitgadget@gmail.com>
In-Reply-To: <pull.1757.v2.git.1720259599119.gitgitgadget@gmail.com>

From: wonda-tea-coffee <lagrange.resolvent@gmail.com>

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.
