When we merged the 4.x branch into master, the Git hook that adds commit messages to Jira failed to complete its execution. I suspect it's because there's a hardcode limit of 100 commits in the script, and the merge was of more than 100 commits. As a result, we have no Git commit messages in Jira for the majority of tickets marked with the 4.0.0 fix version. This makes it hard to track changes to actual commits, and makes it harder to check whether we actually committed a change for each issue we claimed to have fixed.

This task is to write a one-time script that will create the appropriate Jira comments for each commit from the merge. We can start with the regular hook script and hopefully just modify it so that it doesn't fail when there are more than 100 commits.
