This patch has definitely been a mess, so thank you for your time and
sticking with me here. I thought my build tests included these files,
though discovered they did not. Since submitting v2, I was able to reproduce the
same errors you listed and corrected the problem in v3.

I also realized my .git/post-commit file needed to be fixed, so the white
space problem in v1 should also not be a problem in the future.

Please let me know if you notice anything else I can improve on. I will
learn from my mistakes and really appreciate advice. Thank you again, David.

Best Regards,
Kelsey
