Pull request description:

@ -807,7 +807,16 @@ To create a scripted-diff:
- `-BEGIN VERIFY SCRIPT-`
- `-END VERIFY SCRIPT-`
The scripted-diff is verified by the tool `test/lint/commit-script-check.sh`
The scripted-diff is verified by the tool `test/lint/commit-script-check.sh`. The tool's default behavior when supplied
with a commit is to verify all scripted-diffs from the beginning of time up to said commit. Internally, the tool passes
the first supplied argument to `git rev-list --reverse` to determine which commits to verify script-diffs for, ignoring
commits that don't conform to the commit message format described above.
For development, it might be more convenient to verify all scripted-diffs in a range `A..B`, for example:
```bash
test/lint/commit-script-check.sh origin/master..HEAD
```
Commit [`bb81e173`](https://github.com/bitcoin/bitcoin/commit/bb81e173) is an example of a scripted-diff.
