Re: [PATCH 1/3] t3436: check --committer-date-is-author-date result more carefully

[Phillip Wood <phillip.wood123@gmail.com>]

Hi Peff

Thanks for fixing this embarrassing mistake and strengthening the tests, 
the first three patches look fine to me. We don't check the committer 
name and email in t4150-am.sh which we probably should do (the rebase 
tests were based on those) though that can wait as some of the rebase 
tests are testing the am implementation.

Thanks again

Phillip
