Yikes, so I collected commits on March 26, but when I went to add new
commits, I used March 27 as the start date, and missed all the late
March 26 commits.  I should have started on March 26 to get
later-in-the-day commits!

I went back and looked at the commits I missed and the one you pointed
out is the only relevant one, so that is good.

Applied patch attached.
